Convert Variable to lowercase and with -'s instead of spaces?

[Sam Granger]

Hey guys!

 

Lets say I have a variable. Sometimes it contains 1 or more spaces. How can I replace the spaces with '-'?

$string = "This Is A sTrING";

 

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

Don't replace spaces with - or php will think you're trying to subtract things.  Replace the spaces with the underscore character _

surely only when using eval???

 

I don't use underscores in file names - accessibility and all that - if people look at a link to a file and there is an underscore in it while the link has underlined text decoration then they may be confused - just my way if you are consistent then you find you have less problems (as always).  Never had a problem with php thinking I am trying to subtract strings...
