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?

Answer 1

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
