i have a script wrote in perl which i am looking to convert into php. I
have the regular expression

$field =~ s/^,//;

This is to remove a ',' at the start of a string. Does anyonw know what the
equivalent would be in php?? If i use this regualr expression in my php i
get the error

"parse error, unexpected '^'"

Thanks and regards

$field = preg_replace("/^,/", "", $field);

Not equivalent, but probably faster:

$field = ltrim($field, ',');

It will remove _all_ ',' from the beginning of the string.
