removing whitespace from a string?

[smilesinblues@gmail.com]

Hi,
Here is the code I use to change whitespace from a string $test to
hypen -.

<?Php

$test="Teststri ng test test hay man test test test test";

// Chr(32) is ASCI code for whitespace and Chr(45) is for -

$test = str_replace(Chr (32), Chr(45), $test);

echo $test;
?>

My problem is I have to take out the whitespace completely form the
string.

I will be thankful if anyone can help me, or guide me to the function
name that can be used for this.

Thank You for help.

Do exactly the same, but replace it with empty strings.

$test = str_replace(chr (32), "", $test);

Why the chr() function? Why no simply:

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

Well, I just copied the OP's code which had the chr function, but how's this;
if all you want to do is replace the space character chr(32), can you see the
difference between:

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

One of these does not do what you think :-) (Provided it survives the
copy&paste&post process...)

I knew something like that would come up. ;)

But I assume the OP knows what he's doing and what he really wants to
replace. He should be able to hit the right key(s).
