Deleting spaces from a string

Question

I have a form where people enter their multiple codes. Now, I would like to delete the spaces between these codes. However, my code doesnt seem to work. Any ideas?

$codes = $_GET['codes'];
$spaces = strpos($codes, " ");
for($spaces; $spaces=0; $spaces--){
str_replace(" ", "", $codes);
echo $codes;
}

EDIT: I just have tried something else but it still doesnt work at all. I mean the echo gives me the original string every single time.

$codes = $_GET['codes'];
$cleancodes = str_replace(" ", "", $codes);
$cleancodes = trim(preg_replace('/\s\s+/', ' ', $cleancodes));
echo "<br / >" . $cleancodes;

• Rizier123: No for loop, no strpos, just str_replace() ... ?!
• Mihai: Your for loop sets $spaces to 0 so there is nothing to replace,maybe show what you have in $_GET

• Death-is-the-real-truth: can you please show $codes value?

Answer 1

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

Answer 2

$text=str_replace(" ","",$text);

But doing that for code? Bound to break (if you meant program code)!

Answer 3

Use str_replace():-

<?php
$_GET['codes'] = "abc def ghi jkl mno pqr stu vwx yz ";
$codes = $_GET['codes'];
$codes = str_replace(" ","",$codes);
echo $codes;
