How to get full path of image in php

If you mean the path where the image was located on the user computer before he/she uploaded it to your form — you can never know it in php or javascript or anywhere else.

In PHP you can see the path on SERVER (usually in the temporary folder) where the file was stored so you can read or copy it. If may just happen that the server is as well your user computer (i.e. you are testing the website on http :// localhost) but don’t confuse those two things.

You can never be sure of getting a full filepath or even a reliable filename or content-type submitted in a file upload file.

you should never do so. and i think trying it in latest browsers is useless(from what i know) .. all latest browsers on the other hand , will not allow this.

How to join filesystem path strings in PHP?

function join_paths() < $paths = array(); foreach (func_get_args() as $arg) < if ($arg !== '') < $paths[] = $arg; >> return preg_replace('#/+#','/',join('/', $paths)); > 

My solution is simpler and more similar to the way Python os.path.join works

Consider these test cases

array my version @deceze @david_miller @mark ['',''] '' '' '/' '/' ['','/'] '/' '' '/' '/' ['/','a'] '/a' 'a' '//a' '/a' ['/','/a'] '/a' 'a' '//a' '//a' ['abc','def'] 'abc/def' 'abc/def' 'abc/def' 'abc/def' ['abc','/def'] 'abc/def' 'abc/def' 'abc/def' 'abc//def' ['/abc','def'] '/abc/def' 'abc/def' '/abc/def' '/abc/def' ['','foo.jpg'] 'foo.jpg' 'foo.jpg' '/foo.jpg' '/foo.jpg' ['dir','0','a.jpg'] 'dir/0/a.jpg' 'dir/a.jpg' 'dir/0/a.jpg' 'dir/0/a.txt' 

Since this seems to be a popular question and the comments are filling with «features suggestions» or «bug reports». All this code snippet does is join two strings with a slash without duplicating slashes between them. That’s all. No more, no less. It does not evaluate actual paths on the hard disk nor does it actually keep the beginning slash (add that back in if needed, at least you can be sure this code always returns a string without starting slash).

join('/', array(trim("abc/de/", '/'), trim("/fg/x.php", '/'))); 

The end result will always be a path with no slashes at the beginning or end and no double slashes within. Feel free to make a function out of that.

EDIT: Here’s a nice flexible function wrapper for above snippet. You can pass as many path snippets as you want, either as array or separate arguments:

function joinPaths() < $args = func_get_args(); $paths = array(); foreach ($args as $arg) < $paths = array_merge($paths, (array)$arg); >$paths = array_map(create_function('$p', 'return trim($p, "/");'), $paths); $paths = array_filter($paths); return join('/', $paths); > echo joinPaths(array('my/path', 'is', '/an/array')); //or echo joinPaths('my/paths/', '/are/', 'a/r/g/u/m/e/n/t/s/'); 

@deceze’s function doesn’t keep the leading / when trying to join a path that starts with a Unix absolute path, e.g. joinPaths(‘/var/www’, ‘/vhosts/site’); .

function unix_path() < $args = func_get_args(); $paths = array(); foreach($args as $arg) < $paths = array_merge($paths, (array)$arg); >foreach($paths as &$path) < $path = trim($path, '/'); >if (substr($args[0], 0, 1) == '/') < $paths[0] = '/' . $paths[0]; >return join('/', $paths); >

sys_get_temp_dir

Returns the path of the directory PHP stores temporary files in by default.

Parameters

This function has no parameters.

Return Values

Returns the path of the temporary directory.

Examples

Example #1 sys_get_temp_dir() example

// Create a temporary file in the temporary
// files directory using sys_get_temp_dir()
$temp_file = tempnam ( sys_get_temp_dir (), ‘Tux’ );

The above example will output something similar to:

If running on a Linux system where systemd has PrivateTmp=true (which is the default on CentOS 7 and perhaps other newer distros), this function will simply return «/tmp», not the true, much longer, somewhat dynamic path.

As of PHP 5.5.0, you can set the sys_temp_dir INI setting so that this function will return a useful value when the default temporary directory is not an option.

This function does not always add trailing slash. This behaviour is inconsistent across systems, so you have keep an eye on it.

It’s not documented but this function does not send the path with trailing spaces, actually it drops the slash if it exists.

it should be mentioned that the return value of sys_get_temp_dir() can be set using the ini-directive ‘sys_temp_dir’ globally as well as per directory by using
php_admin_value sys_temp_dir /path/to/tmp

A very helpful thing to note when on Linux:

If you are running PHP from the commandline you can use the environment variable: TMPDIR — to change the location without touching php.ini. — This should work on most versions of PHP.

Example file: test.php
echo sys_get_temp_dir () . PHP_EOL ;
?>

And then running:

TMPDIR=/custom/location php test.php
/custom/location

This function does not account for virtualhost-specific modifications to the temp path and/or open_basedir:

php_admin_value open_basedir /home/user
php_admin_value upload_tmp_dir /home/user/tmp
php_admin_value session.save_path /home/user/tmp

Within this config it still returns /tmp

That is important for the purposes of building paths through concatenation to know that sys_get_temp_dir does not include a path separator at the end.

So, sys_get_temp_dir() will return whatever your temp dir is set to, by default:

If you attempted to concatenate another dir name temp and use the following:

That would actually attempt to generate:
/tmpsome_dir

It would likely result in a permission error unless you are running a php script as a super user.

Instead you would want to do:
mkdir( sys_get_temp_dir() . DIRECTORY_SEPARATOR. ‘some_dir’ );

which would create:
/tmp/some_dir

I don’t know if Windows or other platforms include a directory separator at the end. So if you are writing something a bit more general you may want to check for the path separator at the end and if it is not there append it.

On windows, when PHP is used as CLI, this function will return the temp directory for the current user e.g. C:\Users\JohnSmith\AppData\Local\Temp\9 instead of C:\Windows\Temp.

Create and Get the Path of tmpfile in PHP

1. Use the stream_get_meta_data() Function and uri Index to Create and Get the Path of tmpfile in PHP
2. Use the tempnam() and sys_get_temp_dir() Functions to Create and Get the Path of tmpfile in PHP

This article will introduce methods to create temporary files and get their full path in PHP.

Use the stream_get_meta_data() Function and uri Index to Create and Get the Path of tmpfile in PHP

Temporary files are the files that hold the information temporarily while the program executes. Once the script or the program finishes its execution, the temporary file is deleted or transferred to a permanent file.

We can create temporary files in PHP with the tmpfile() function.

The temporary file created by the function has the read/write(w+) mode. It returns false in case of failure to make a temporary file.

We can use stream_get_meta_data() to get the path of the temporary file. The function takes a parameter that can be streams or file pointers.

It receives the header or metadata from the parameter and returns an array. We can use the file pointer of the temporary file created by the tmpfile() function and the uri index to return the temporary file path.

For example, create a temporay file with the tmpfile() function and store it in the $file variable. Next, use the stream_get_meta_data() function with $file as the parameter.

Assign it to the $temp_path variable. Finally, display the variable using the uri index.

As a result, we can see the temporary file’s location.

$file = tmpfile(); $temp_path = stream_get_meta_data($file); echo $temp_path['uri']; 

Use the tempnam() and sys_get_temp_dir() Functions to Create and Get the Path of tmpfile in PHP

We can also use the tempnam() function to create a temporary file in PHP. Using this function, we can give a unique name to the file.

The function takes two parameters. The first parameter specifies the directory where the temporary file is to be created, and the second is the filename prefix.

We can use the sys_get_temp_dir() function as the first parameter to the tempnam() function. The sys_get_temp_dir() function returns the default directory where PHP stores the temporary file.

As a result, a temporary file will be created in the default directory. We can get the temporary file path by displaying the tempnam() function with echo .

For example, create a variable $temp_path and assign it with the tempnam() function. Write the sys_get_temp_dir() function as the first parameter to the function and php as the prefix.

Next, use the echo function to print the $temp_path variable.

Consequently, the path of the temporary file is printed.

$temp_path = tempnam(sys_get_temp_dir(), 'php'); echo $temp_path;

PHP way to find the web server’s temp path?

I know I could extract the temp path from there. But I was expecting maybe a $_SERVER param that had the temp path (there’s none) or other elegant way of knowing it. Is there any?

This is probably the more correct answer, as the upload temp dir may be different from the system temp dir.

Be aware: not all web servers set upload_tmp_dir . You’re better off following @NateGlenn’s suggestion of falling back to sys_get_temp_dir() if ini_get(‘upload_tmp_dir’) returns an empty string.

The function sys_get_temp_dir() returns the directory path used by PHP to store temporary files.

Using XAMPP on my private computer, the ini_get method worked great, since php.ini specifies the value upload_tmp_dir . However, after uploading to my employer’s server, this code didn’t work because the value apparently didn’t exist in his server’s php.ini file. So, I used the system’s temp dir as the default, and now the script works on my computer and on his server:

$ini_val = ini_get('upload_tmp_dir'); $upload_tmp_dir = $ini_val ? $ini_val : sys_get_temp_dir(); 

I personally would use Sbm007’s suggestion of:

As this takes into account apache per virtualhost settings like the upload_tmp_dir and open_basedir restrictions, where as :

Would only return the OS’s specific temp directory, and if inside a multi-hosted environment could give you a directory you can’t write to.
