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：

$types = ''; //initial sting with types
foreach($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。
