Here is a function that replaces all occurrences of a number in a string by the number-- <?php function decremente_chaine($chaine) { //récupérer toutes les occurrences de nombres et leurs indices preg_match_all("/[0-9]+/",$chaine,$out,PREG_OFFSET_CAPTURE); //parcourir les occurrences for($i=0;$i<sizeof($out[0]);$i++) { $longueurnombre = strlen((string)$out[0][$i][0]); $taillechaine = strlen($chaine); // découper la chaine en 3 morceaux $debut = substr($chaine,0,$out[0][$i][1]); $milieu = ($out[0][$i][0])-1; $fin = substr($chaine,$out[0][$i][1]+$longueurnombre,$taillechaine); // si c'est 10,100,1000 etc. on décale tout de 1 car le résultat comporte un chiffre de moins if(preg_match('#[1][0]+$#', $out[0][$i][0])) { for($j = $i+1;$j<sizeof($out[0]);$j++) { $out[0][$j][1] = $out[0][$j][1] -1; } } $chaine = $debut.$milieu.$fin; } return $chaine; } ?> ---- Server IP: 69.147.83.199 Probable Submitter: 80.15.50.242 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match-all.php Edit -- https://master.php.net/note/edit/110147 Del: integrated -- https://master.php.net/note/delete/110147/integrated Del: useless -- https://master.php.net/note/delete/110147/useless Del: bad code -- https://master.php.net/note/delete/110147/bad+code Del: spam -- https://master.php.net/note/delete/110147/spam Del: non-english -- https://master.php.net/note/delete/110147/non-english Del: in docs -- https://master.php.net/note/delete/110147/in+docs Del: other reasons-- https://master.php.net/note/delete/110147 Reject -- https://master.php.net/note/reject/110147 Search -- https://master.php.net/manage/user-notes.php
