Note Submitter: e dot anziani at orange dot fr ---- An very simple solution to this problem may be: if($a=="0"){$a=0;}; if($a=="1"){$a=1;}; if($a=="2"){$a=2;}; if($a=="3"){$a=3;}; if($a=="4"){$a=4;}; if($a=="5"){$a=5;}; if($a=="6"){$a=6;}; if($a=="7"){$a=7;}; if($a=="8"){$a=8;}; if($a=="9"){$a=9;}; $a represents an string who becomes an integer. If the variable $a is an number , it's possible to use the function substr() with a iteration like while.
