MySQL SPACE() function

MySQL SPACE() returns the string containing a number of spaces specified as an argument.

This function is useful in —

  • Padding: A string of spaces can be used to pad or align text or numbers.
  • Formatting: SPACE() can be used to create spaces for formatting purposes, such as indenting or aligning columns.
  • Placeholder generation: The SPACE() function can be used to generate a string of spaces as a placeholder for future data.

MySQL Version: 8.0

Example -1: MySQL SPACE() function

Explanation:

The above MySQL statement returns a string containing 10 number of spaces displayed in column alias SPACE(10) in the output.

mysql> SELECT 'start', SPACE(10), 'end'; +-------+------------+-----+ | start | SPACE(10) | end | +-------+------------+-----+ | start | | end | +-------+------------+-----+ 1 row in set (0.00 sec)

Example -2: MySQL SPACE() function

The above MySQL statement returns a string containing 10 number of spaces as column alias space(10) along with columns ‘aut_id’ and ‘aut_name’ for those rows from the table author which have the column value of country as the ‘USA’.

SELECT aut_id,aut_name,aut_id,space(10), aut_name FROM author WHERE country='USA'; 
mysql> SELECT aut_id,aut_name,aut_id,space(10), aut_name -> FROM author -> WHERE country='USA'; +--------+---------------+--------+------------+---------------+ | aut_id | aut_name | aut_id | space(10) | aut_name | +--------+---------------+--------+------------+---------------+ | AUT006 | Thomas Merton | AUT006 | | Thomas Merton | | AUT008 | Nikolai Dewey | AUT008 | | Nikolai Dewey | | AUT010 | Joseph Milton | AUT010 | | Joseph Milton | | AUT015 | Butler Andre | AUT015 | | Butler Andre | +--------+---------------+--------+------------+---------------+ 4 rows in set (0.00 sec)

ctype_space

Проверяет, все ли символы в переданной строке text являются пробельными.

Список параметров

Замечание:

Если передано целое число ( int ) в диапазоне между -128 и 255 включительно, то оно будет обработано как ASCII-код одного символа (к отрицательным значениям будет прибавлено 256 для возможности представления символов из расширенного диапазона ASCII). Любое другое целое число будет обработано как строка, содержащая десятичные цифры этого числа.

Начиная с PHP 8.1.0, передача нестроковых аргументов устарела. В будущем аргумент будет интерпретироваться как строка вместо кода ASCII. В зависимости от предполагаемого поведения аргумент должен быть приведён к строке ( string ) или должен быть сделан явный вызов функции chr() .

Возвращаемые значения

Возвращает true , если каждый символ в строке text создаёт какое-то из пустое пространство, false в противном случае. Кроме пробела, сюда также входят символы табуляции, вертикальной табуляции, перевода строки, возврата каретки и перевода страницы. При вызове с пустой строкой результатом всегда будет false .

Примеры

Пример #1 Пример использования ctype_space()

$strings = array(
‘string1’ => «\n\r\t» ,
‘string2’ => «\narf12» ,
‘string3’ => ‘\n\r\t’ // Обратите внимание, что кавычки одинарные
);
foreach ( $strings as $name => $testcase ) if ( ctype_space ( $testcase )) echo «Строка ‘ $name ‘ состоит только из пробельных символов.\n» ;
> else echo «Строка ‘ $name ‘ состоит не только из пробельных символов.\n» ;
>
>
?>

Результат выполнения данного примера:

Строка 'string1' состоит только из пробельных символов. Строка 'string2' состоит не только из пробельных символов. Строка 'string3' состоит не только из пробельных символов.

A function I wrote last night was fairly flexible in terms of detecting whitespace, and even took into account the pesky non-breaking spaces / zero-width spaces further up the Unicode alphabet.

The benefit here was being able to isolate and identify specific Unicode indices based on their subrange.

// Returns TRUE if the ASCII value of $string matches a registered whitespace character.
// * This includes non-breaking spaces, zero-width spaces, and any unicode values below 32.
// * $string: Character to identify. If string extends past one character, the value
// is truncated and only the initial character is examined.
function is_whitespace ( $string ) <
// Return FALSE if passed an empty string.
if( $string == «» ) return FALSE ;

// Additional Characters
switch( $char ) <
case 160 : // Non-Breaking Space
case 8287 : // Medium Mathematical Space
return TRUE ;
break;
>
return FALSE ;
>
?>

thanks to gardnerjohng, but a had some problems with non-breaking spaces in this function.

I added 2 more cases for this:
case 0xC2
case 0xA0

After this modification non-breaking spaces in my test code were successfully detected.

How to add space in php

Now if you simply want to add 300 spaces (not pad it so that there will be less than 300 spaces) you’ll want to use Question: I am trying to add tab space to php function. Solution 1: You can send the email as HTML which requires extra headers and actual HTML in your message body: Solution 2: Add and : to indicate the message is HTML formatted.

Adding 300 spaces with PHP for text file

I want to add 300 spaces to a text file with PHP. I can’t use &nbsp as you already knew (.txt format, not HTML), so how to do this?

So this code counts numbers as you can see, I need 300 white-spaces.

$spaces = 0; // will become 300 spaces while ($spaces

and for testing how many white-spaces I have I will use

Instead of creating a loop to build them, just use the following

$padded_text = str_pad($some_text, 300, ' ', STR_PAD_LEFT);

Anything less than 300 chars big, gets spaces added, and depending where you want those spaces, you can try using STR_PAD_RIGHT or STR_PAD_BOTH. And if you have no characters at all, it will generate it full of 300 spaces, this will be faster than using a loop.

Now if you simply want to add 300 spaces (not pad it so that there will be less than 300 spaces) you’ll want to use

Adding a non breaking space to a php email does not insert spaces

mail($email, $subject, "Welcome to **!\n\n The password for your account is:\n $password", $headers);

Adding &nbsp to the php email content does not insert spaces.

I want to put two spaces between the colon and $password . Is there a way to add spaces?

You can send the email as HTML which requires extra headers and actual HTML in your message body:

// Add extra headers to $headers $headers .= "MIME-Version: 1.0\r\n"; $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; // Send mail as HTML mail($email, $subject, "Welcome to **!
 
The password for your account is: 
 $password", $headers);

Add and : to indicate the message is HTML formatted. Then you can use  

Use the nl2br function to convert newlines to
s.

Also set the Content-Type by appending a header » Content-Type: text/html; charset=UTF-8 «.

If you don’t want to use HTML: you can use the tab-character \t too, but not sure if Hotmail supports that eighter.

This really depends on what you are reading it in. The problem with Hotmail is that it sees it as plan text, but converts it to HTML most likely to display to you.

Look at example 4 on how to send html email using php.

If the e-mail’s Content-Type is text/plain , then all spaces should be honored. Sounds like you’re transmitting the e-mail message as text/html , which is why you would need the &nbsp to get the second space to show up.

Php — Add whitespace after comma, Add a comment | 2 Instead of using the + quantifier, which matches 1 or more whitespaces, use the <2, >quantifier, which will match just 2 or more whitespaces», hello» won’t match that.

Insert Enters/Spaces of Text in PhpMyAdmin

I have the image and the text of the image that i want to show in my database.

I show the image but i have problems with the text. The text dont show the ENTERS/SPACES. There are some ways to resolve this?

Image of problem: http://imgur.com/wOGo5I5,oUxMcaS

I want this: http://imgur.com/wOGo5I5,oUxMcaS#1

In database text is saving with enters/spaces.

maybe something is wrong on the encoding of connection. in that sql_connect.php file, after you connect, please execute this one:

mysql_query("SET NAMES 'utf8'");

if this doesn’t help, try this one:

mysql_query("SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8'", $conn);

where $conn is your connection. This will make sure everything is UTF-8

Also please make sure the column on your tables are utf8_general_ci

After all this, please re-enter your data to your db and try again.
