basic string replacement

[Gonzillaaa]

If I have a string such as "/ Support us / Volunteering" how do I get
rid of the first slash and not both of them? I had a go at ltrim but
with no success. $path = ltrim($path, "/")
Thanks,

$path=preg_replace('`/\s*`','',$path,1);

Thanks Justin

I've always found regular expression intimidating.

I was always surprised that PHP didn't have a "limit" argument for
str_replace() that would limit the number of replacements made. If
anyone is interested, I wrote this guy. There's probably a better way,
but it seems to work:

function str_replace_limit($search, $replace, $subject, $limit, &$count
= null) {
$count = 0;

if($limit == 0 || strpos($subject, $search) === false)
return $subject;

$pos = 0;
for($i = 0; $i < $limit; $i++) {
$pos = strpos($subject, $search, $pos);
if($pos === false)
return str_replace($search, $replace, $subject, $count);

$pos += strlen($search);
}

$count = $limit;
$pre = str_replace($search, $replace, substr($subject, 0, $pos));
$post = substr($subject, $pos);

return $pre . $post;
} //str_replace_limit
