How to remove a whitespace in php even if its not detected

Question

I'm trying to remove a whitespace from a string, but this whitespace its not detected, i've tried so many solutions like str_replace(), preg_replace() htmlentities() an html_entity_decode() but its not working because i can't detect this whitespace even if it's really present.

So any ideas please ?

An example : 7412 148 ==> The goal is : 7412148 PS : i've tried to convert it to INT (not working) !

Thanks

where does the string come from and what do you want to do with it? — Fanax, Oct 23 '15 at 08:52
is the whitespace at the beginning, the end or inside the string, can you provide some sample so we can get a better understanding? — Alex Andrei, Oct 23 '15 at 08:53
the string returned from a function, when i do a var_dump() i can see that's a string. — karim karim, Oct 23 '15 at 08:54
@karimkarim There might be a case that some hidden characters exist instead of whitespace. And somehow browser could not render that character. — sandeepsure, Oct 23 '15 at 08:58

Let's use preg_replace to replace/remove everything that is not a digit.

$str = "1234 5657"; // this is an example

$number = preg_replace("/[^0-9]/","",$str);

print $number;

Use this with the string that your function returns and let us know if it works.
