How do I strip all spaces out of a string in PHP

Question

How can I ensure removing all spaces of a string in PHP?

I have a string:- $string = "this is my string";

The output should be "thisismystring"

How can I do that?

Answer 1

If I have understood your question right, you mean spaces or all whitespace? For both, there are solutions as mentioned below:-

For just spaces, use str_replace:
 

$string = str_replace(' ', '', $string);

For all whitespace (including tabs and line ends), use preg_replace:
 

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