How to remove all white spaces from a string in PHP ?
Given a string element containing some spaces and the task is to remove all the spaces from the given string str in PHP. In order to do this task, we have the following methods in PHP:
Method 1: Using str_replace() Method: The str_replace() method is used to replace all the occurrences of the search string (” “) by replacing string (“”) in the given string str.
Syntax:
str_replace($searchVal, $replaceVal, $subjectVal, $count)
Example :
PHP
<?php
$str = " Geeks for Geeks " ;
$str = str_replace ( ' ' , '' , $str );
echo $str ;
?>
|
Method 2: Using str_ireplace() Method: The str_ireplace() method is used to replace all the occurrences of the search string (” “) by replacing string (“”) in the given string str. The difference between str_replace and str_ireplace is that str_ireplace is a case-insensitive.
Syntax:
str_ireplace($searchVal, $replaceVal, $subjectVal, $count)
Example :
PHP
<?php
$str = " Geeks for Geeks " ;
$str = str_ireplace ( ' ' , '' , $str );
echo $str ;
?>
|
Method 3: Using preg_replace() Method: The preg_replace() method is used to perform a regular expression for search and replace the content.
Syntax:
preg_replace( $pattern, $replacement, $subject, $limit, $count )
Example :
PHP
<?php
$str = " Geeks for Geeks " ;
$str = preg_replace( '/\s+/' , '' , $str );
echo $str ;
?>
