How to detect leading zeros

[realjumper]

Hi,

 

The student id that is entered into a form is always a string of numbers....and no student numbers ever start with zero ('0'). Yet, some student has entered a zero before his student number...sigh! So, how can I detect whether the first interger in the string is a '0', and if it is, strip it out? I'm searching for the answer as we speak, but you may have an idea.

 

Many thanks,

<?php
$studentID = "0002345607"; 
$result = preg_replace('/^0+/', "", $studentID);
echo $result; //2345607
?>

 

Try this. Make sure that the ID is a string, otherwise it will output some funny answers.

Oh that's perfect....thank you :-)

$studentID = round($studentID);

 

So do you work for a school in New Zealand? I work for a school district and I used to work for a NZ based company?

intval() might work too, if the ID number is only numbers.
