PHP string removes space

Question

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

How to do it? Thank you

Answer 1

Following will work

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

or

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

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

Answer 2

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

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

Answer 3

 $string = preg_replace('/\s+/', '', $string);
