realjumper Posted February 23, 2007 Share Posted February 23, 2007 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, Neil Link to comment https://forums.phpfreaks.com/topic/39739-how-to-detect-leading-zeros/ Share on other sites More sharing options...
JBS103 Posted February 23, 2007 Share Posted February 23, 2007 <?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.

artacus Posted February 23, 2007 Share Posted February 23, 2007 $studentID = round($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?

Jessica Posted February 23, 2007 Share Posted February 23, 2007 intval() might work too, if the ID number is only numbers. Link to comment https://forums.phpfreaks.com/topic/39739-how-to-detect-leading-zeros/#findComment-191953 Share on other sites More sharing options...
