Php strpos empty delimiter

What does Warning: strpos() [function.strpos]: Empty delimiter in mean?

Answers

At a guess, I’d say $text is an empty string (thanks Mark for pointing out the specifics)

Edit: Also, another guess is you have the parameters in the wrong order. The method signature of strpos is

int strpos ( string $haystack , mixed $needle [, int $offset = 0 ] ) 

Here’s what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install $ pecl uninstall -r $ pecl -d php_suffix=7.0 install $ pecl uninstall -r $ pecl -d php_suffix=7.1 install $ pecl uninstall -r

The -d php_suffix= piece allows you to set config values at run time vs pre-setting them with pecl config-set . The uninstall -r bit does not actually uninstall it (from the docs):

[email protected]:~$ pecl help uninstall pecl uninstall [options] [channel/] . Uninstalls one or more PEAR packages. More than one package may be specified at once. Prefix with channel name to uninstall from a channel not in your default channel (pecl.php.net) Options: . -r, --register-only do not remove files, only register the packages as not installed . 

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

How do I resolve a strpos() «empty delimiter» error?

This error occurs when the second parameter to strpos is empty. For instance, I can easily simulate this error at the command line:

$ php ^D Warning: strpos(): Empty delimiter in - on line 2 

In your code, it means that $fgParams->get(‘base’) is empty.

Add some checks to your code to ensure that the values you pass to strpos are valid, and the error will go away.

Solution 2

if($src = $img->getAttribute('src') AND strpos($src,$fgParams->get('base')) === false) < // prevents repeat processing 

if($src = $img->getAttribute('src') AND $fgParams->get('base')!="" AND strpos($src,$fgParams->get('base')) === false) < // prevents repeat processing 

Seems like that get('base') is returning nothing. Is this possible in your script? perhaps it's the indication of a previous error in another area of the program.

Please make sure that value of $fgParams->get('base') is not blank as json mentioned in condition.

I had the same problem with:

if (htmlentities($controleren[$aantaltekens] == htmlentities($trans[$tellen]) 

The error disappeared when I added the two () delimiters:

if (htmlentities($controleren[$aantaltekens]) == htmlentities($trans[$tellen])) 

if(($src = $img->getAttribute('src') AND strpos($src,$fgParams->get('base'))) === false) 

Guess htmlentities requires its parameters to be within (delimiters).

if($src = $img->getAttribute('src') AND strpos($src,$fgParams->get('base')) === false) < // prevents repeat processing 

if($src = $img->getAttribute('src') AND $fgParams->get('base')!="" AND strpos($src,$fgParams->get('base')) === false) < // prevents repeat processing 

Seems like that get('base') is returning nothing. Is this possible in your script? perhaps it's the indication of a previous error in another area of the program.
