本文實例講述了php動態綁定變量的用法。分享給大家供大家參考。具體如下：

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

//go through incoming params and added em to array

$bind_name = ‘bind‘ . $i;

//give them an arbitrary name

$$bind_name = $params[$i];

//add the parameter to the variable variable

$bind_names[] = &$$bind_name;

//now associate the variable as an element in an array

}

//call the function bind_param with dynamic params

call_user_func_array(array($stmt,‘bind_param‘),$bind_names);

}

return $stmt; //return the bound statement

希望本文所述對大家的php程序設計有所幫助。
