How to Replace Special Characters in PHP

Hi

When we what to do things like 

I have a string like $string = "this is my string"; the output should be "thisismystring" or
Or "this_is_my_string"


I want to  Replace white Space or Space or " " from text in php 

or just replace white space with underscore ??

or replace any Special character from text 
How can i do that?


Answer is

For just spaces, use str_replace:
Syntax:
str_replace('Character to replace' ,'Replace by','Source String');

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

For all whitespace, use preg_replace:

preg_replace('Character to replace' ,'Replace by','Source String');

/\s+/ used for all type White Space; 

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