preg_match question

[jeff5656]

Hi I am not well versed in regular expression.

I have in the $patient field,  "smith, john"

 

Using preg_match, how would I write it so it only echo out Smith?  In other words, echo everything up to the comma.  Thanks!

RegEx isn't required here, so i posted a non-regEx version as well

 

$patient = "smith, john";
if (preg_match('/(.*?),/sim', $patient, $regs)) {
$fName = $regs[1];
}
echo $fName;

//OR
echo substr($patient, 0, strrpos($patient, ","));

 

hope they helps

(oh both are untested)
