How to Strip All Spaces Out of a String in PHP
Topic: PHP / MySQLPrev|Next
Answer: Use the PHP str_replace()
Function
You can simply use the PHP str_replace()
function to strip or remove all spaces inside a string.
Let's take a look at the following example to see how it actually works:
Example
Try this code »<?php
$str = 'This is a simple piece of text.';
$new_str = str_replace(' ', '', $str);
echo $new_str; // Outputs: Thisisasimplepieceoftext.
?>
The above example will however only remove spaces. If you want to remove all whitespaces including tabs, newlines, etc. you can use the preg_replace()
function which perform a regular expression search and replace, as demonstrated in the following example:
Example
Try this code »<?php
$str = "This is a simple \npiece\tof text.";
$new_str = preg_replace("/\s+/", "", $str);
echo $new_str; // Outputs: Thisisasimplepieceoftext.
?>
In the above example \t
represents the tab character, whereas \n
represents the newline character.
