checking if spaces in string

[brown2005]

hi i need to check if there are spaces in a string...

example if someone enters a username like

brown 2005

it will say 1 space

or if

brown2005

it will say 0 spaces

thanks

I'm not sure, but something like [code]$spaces = preg_match('/ /',$username);[/code] should do it. I haven't tested it though.

well, daniel0 has a great start, but if you're looking to actually count the spaces, i would recommend something like this:
[code]
<?php
$string = "username 2005";
$spaces = preg_replace('|[^ ]|', '||', $string);
echo "There are " . strlen($spaces) . " spaces.";
?>
[/code]

good luck

hi that actually says 1 when there are not no spaces mate?

my bad... you don't need the || inside the second set of quotes :P
[code]
<?php
$string = "username2005";
$spaces = preg_replace('|[^ ]|', '', $string);
echo "There are " . strlen($spaces) . " spaces.";
?>
[/code]

nope just stays on 0

Put spaces in the $string variable first. ege:
$string = "  username  2005  ";
Should say there are 9 spaces
