PHP string remove space.

Question

Is there php function to remove the space inside the string? for example: $abcd="this is a test" I want to get the string: $abcd="thisisatest"

How to do that? thanks.

Answer 1

$abcd = str_replace(' ', '', 'this is a test');

See http://de.php.net/manual/en/function.str-replace.php

Answer 2

The following will also work

$abcd="this is a test";
$abcd = preg_replace('/( *)/', '', $abcd);
echo $abcd."\n"; //Will output 'thisisatest';

or

$abcd = preg_replace('/\s/', '', $abcd);

See manual http://php.net/manual/en/function.preg-replace.php
