I had problem using is_numeric() to verify if user inputs is a number (including optional floating sign and decimals). Instead I found this expression from http://www.regular-expressions.info/floatingpoint.html and modified it for a bit. ^[+-]?[0-9]*\.?[0-9]+$ /* 3.55 true -3.55 true +3.55 true 2456.90 true 34skd false 23. false 2dt6 false */ Note: mine doesn't have the exponent part; for matching number with exponents, visit the site above :) ---- Manual Page -- http://www.php.net/manual/en/function.ereg.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59755 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59755&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59755&report=yes Search -- http://master.php.net/manage/user-notes.php
