How do I remove all places in a string?

I want to remove all spaces and replace them with -'s from a posted row in mysql database after it is submitted to the form...so that I can use it in a URL without getting %20%, this is what I have...

$q_title_ = str_replace(" ", "-", "{$_POST['q_title']}");
$directory = "../question/{$_POST['category']}/$q_title_/";
mkdir("$directory", 0777);

any idea what I'm doing wrong?

 

try this

dont use {} on line 2

 

What sunnyverma1984 suggested won't work, it'll cause a syntax error.

Your code, other than its formatting, seems okay. Can you be more specific as to what doesn't work exactly? Do you get some error? A blank page? Unexpected result of some kind? A dinasure attack you? Its really hard to say what's wrong when you don't say what's not working.

 

try this:

$q_title_ = str_replace(" ", "-", $_POST['q_title']);
$directory = "../question/".$_POST['category']."/".$q_title_."/";
mkdir($directory, 0777);

Code (markup):

 

Cool.. trying tweak with wordpress...

 

Try this

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