Using preg_replace to insert a space for every _

Micah_D

Thats it, I want to insert a splace for every underscore.


function Repalce_With_Space($input) {
   // Replace spaces with Percentages
   $output = preg_replace("/_/e" , ' ' , $input);

   return $output;
}

But when I use " " or ' ' with the space it replaces the underscore with nothing. I am sure there's a \space or something like that I can use?

Thanks for the help.

why aren't you using [man]str_replace[/man] for such a simple thing.

You don't need the /e modifier. That says the replacement text should be interpreted as PHP code; and in PHP a blank space doesn't do very much!

In fact, you don't need preg_replace (and, given its processing overhead, if you don't need it then you shouldn't use it). Have a look at using [man]str_replace[/man] or [man]strtr[/man] instead.

Hi Micah_D, try doing this instead:

function Repalce_With_Space($input) {
   // Replace spaces with Percentages
   $output = preg_replace("/_/" , chr(32) , $input);

   return $output;
}

dalar

 $output = preg_replace("/_/" , chr(32) , $input);

exactly what I was going to suggest, nice one yktan! 🙂

No need for preg_replace. And as far as I know, str_replace is faster (??)

Thanks dalar, I'm but a newbie in RegEx, so I'm happy that it works 😛
