mysql - Php Str_replace with a for loop -


i'm trying give each textarea name can use them later send database. code got weird results , guess because use str_replace.

here's code:

$description2 = mysql_result($product, 0, 'productdescription2'); $totalteknisk = preg_match_all('/x(a|b|d|e)/', $description2, $matches); $searcharray = array('xa', 'xb', 'xc', 'xd', 'xe');  if ($description2 !=""){ for($z=1;$z <= $totalteknisk; $z++){ $xa = '<textarea name="'. $z .'" style="background-color:#ffffff;resize: none; height: 20px; width: 200px;">'; $z++; $xb ='</textarea><textarea name="'. $z .'" style="background-color:#ffffff;resize: none; height: 20px; width: 200px;">'; $z++; $xc = '</textarea><br>'; $xd = '<textarea name="'. $z .'" style="background-color:#eaf2d3;resize: none; height: 20px; width: 200px;">'; $z++; $xe = '</textarea><textarea name="'. $z .'" style="background-color:#eaf2d3;resize: none; height: 20px; width: 200px;">'; $replacearray = array($xa, $xb, $xc, $xd, $xe); $teknisk .=  str_replace($searcharray, $replacearray, $description2);    }                                }

example string database xa1xb2xcxd3xe4xcxa5xb6xc(description2)

as can see i'm trying loop , give value 1 $totalteknisk.

i'm open suggestions on how can make work.

i solved bit differently, using preg_replace_callback(...)

$description2 = 'xa1xb2xcxd3xe4xcxa5xb6xc';  $html = preg_replace_callback('/x(?:a|b|c|d|e)/', function($match) {     static $count;      $count++;      switch($match[0]) {         case 'xa':             return "<textarea name=\"$count\" style=\"background-color:#ffffff;resize: none; height: 20px; width: 200px;\">";         case 'xb':             return "</textarea><textarea name=\"$count\" style=\"background-color:#ffffff;resize: none; height: 20px; width: 200px;\">";         case 'xc':             return "</textarea><br />";         case 'xd':             return "<textarea name=\"$count\" style=\"background-color:#eaf2d3;resize: none; height: 20px; width: 200px;\">";         case 'xe':             return "</textarea><textarea name=\"$count\" style=\"background-color:#eaf2d3;resize: none; height: 20px; width: 200px;\">";     } }, $description2);  $teknisk .= $html;

i suggest, dont use numbers 'name' attribute in textareas. may should consider using name, fields[$count] , refer $_post['fields'] ...
