Finding spaces in a string

[tcorbeil]

Hello gain.

 

I am now looking for a way to go through a string variable, find any space that is present and replace it with _.

 

How would I go about?

 

The reason is I get input from a user.. lets say he/she loads a variable $Hockey = "Edmonton Oilers";

 

this variable is used to create a new webpage but of course, the web does not like spaces.. hence I would need this variable to be $Hockey = "Edmonton_Oilers";

 

Any help would be much appreciated.

$string = str_replace(" ", "_", $string);

 

or replace anything that is not a character with an underscore so, +_)(*&^%$#@~!{}|:">?<,/.';\[]

 

$string = ereg_replace("[^[:alpha:]]", "_", $string);

If you're wanting to replace tab characters and newlines as well (assuming they may have copied and pasted from another location), you'll need to be more generic with your spacing matches:

<?php
$string = preg_replace('|\s+|', '_', $string);
?>

 

This will also interpret multiple spaces within the string to a single underscore so you don't end up with "Edmonton_____Oilers"

Thanks mjlogan. Works like a charm!
