php动态绑定变量的用法

本文实例讲述了php动态绑定变量的用法。分享给大家供大家参考。具体如下：

private function bindVars($stmt,$params) {
  if ($params != null) {
    $types = ''; //initial sting with types
    foreach($params as $param) {
 //for each element, determine type and add
      if(is_int($param)) {
 $types .= 'i'; //integer
      } elseif (is_float($param)) {
 $types .= 'd'; //double
      } elseif (is_string($param)) {
 $types .= 's'; //string
      } else {
 $types .= 'b';
 //blob and unknown
      }
    }
    $bind_names[] = $types;
 //first param needed is the type string
 // eg: 'issss'
    for ($i=0; $i

希望本文所述对大家的php程序设计有所帮助。
