Das ist, was ich zu tun verwenden Mysqli vorbereitete Anweisungen mit einer variablen Menge von params. Es ist Teil einer Klasse, die ich geschrieben habe. Es ist wahrscheinlich Overkill für das, was Sie brauchen, aber es sollte Ihnen die richtige Richtung zeigen.
public function __construct($con, $query){
$this->con = $con;
$this->query = $query;
parent::__construct($con, $query);
//We check for errors:
if($this->con->error) throw new Exception($this->con->error);
}
protected static $allowed = array('d', 'i', 's', 'b'); //allowed types
protected static function mysqliContentType($value) {
if(is_string($value)) $type = 's';
elseif(is_float($value)) $type = 'd';
elseif(is_int($value)) $type = 'i';
else throw new Exception("type of '$value' is not string, int or float");
return $type;
}
//This function checks if a given string is an allowed mysqli content type for prepared statement (s, d, b, or i)
protected static function mysqliAllowedContentType($s){
return in_array($s, self::$allowed);
}
public function feed($params){
//These should all be empty in case this gets used multiple times
$this->paramArgs = array();
$this->typestring = '';
$this->params = $params;
$this->paramArgs[0] = '';
$i = 0;
foreach($this->params as $value){
//We check the type:
if(is_array($value)){
$temp = array_keys($value);
$type = $temp[0];
$this->params[$i] = $value[$type];
if(!self::mysqliAllowedContentType($type)){
$type = self::mysqliContentType($value[$type]);
}
}
else{
$type = self::mysqliContentType($value);
}
$this->typestring .= $type;
//We build the array of values we pass to the bind_params function
//We add a refrence to the value of the array to the array we will pass to the call_user_func_array function. Thus say we have the following
//$this->params array:
//$this->params[0] = 'foo';
//$this->params[1] = 4;
//$this->paramArgs will become:
//$this->paramArgs[0] = 'si'; //Typestring
//$this->paramArgs[1] = &$this->params[0];
//$this->paramArgs[2] = &$this->params[1].
//Thus using call_user_func_array will call $this->bind_param() (which is inherented from the mysqli_stmt class) like this:
//$this->bind_param('si', &$this->params[0], &$this->params[1]);
$this->paramArgs[] = &$this->params[$i];
$i++;
}
unset($i);
$this->paramArgs[0] = $this->typestring;
return call_user_func_array(array(&$this, 'bind_param'), $this->paramArgs);
}
Sie verwenden es wie folgt aus:
$prep = new theClassAboveHere($mysqli, $query);
$prep->feed(array('string', 1, array('b', 'BLOB DATA'));
Die Klasse sollte die mysqli_stmt Klasse erweitern.
Ich hoffe, das hilft Ihnen in die richtige Richtung.
Wenn Sie möchten, könnte ich auch die gesamte Klasse buchen, es enthält variable Ergebnisse Bindung.
