trim() help

I want ot filter out commas from the beginning and end of a sentence. Here is the code that I was trying to use:

$trimmed = trim($text,",");

I get this error when I do that:
Warning: Wrong parameter count for trim()

I dont understand why this is happening, can somebody show me my error? Thanks

trim() is just for whitespace. You need to use the ereg() functions, for example:

// From the beginning
$string = ereg_replace(\"^,\", \"\", $string);

// From the end
$string = ereg_replace(\",$\", \"\", $string);

If you have whitespace as well, you\'ll need to run trim() first.

RTFM & HTH,

$trimmed=eregi_replace("^{,(.*),$","\1",trim($text));}

That should do it

input: $text
output: $trimmed

the trim() is merely precautionary and will get rid of any whitespace at each end of the string, which would foul up the regexp.
