我有一个数学解析器库,但是它包含一个简单的错误。类中抛出了一些方法,并且有这样的调用:
ItemID FID1 FID2 FID3 FName1 FName2 FName3
100084 2545 2536 2535 Name 1 Name 2 Name 3
当此方法调用类的魔术方法时,当我调用此类函数时,该函数将起作用
class Mathparser_NParamNode extends Mathparser_Node {
public $nodes; //array of nodes (these are the parameters).
public $fPtr; //function to execute
public function __construct($n, $FuncAddr) {
$this->nodes = &$n;
$this->fPtr = $FuncAddr;
}
public function getValue() {
if($this->fPtr->Name=='IF'){
//special case for short circuit boolean logic.
//helps to avoid div by zero etc.
//assume there are 3 parameters:
$cond = $this->nodes[0]->getValue();
if($cond==0){ //false:
return $this->nodes[2]->getValue();
}else{
return $this->nodes[1]->getValue();
}
}else{
$p = array();
$count = count($this->nodes);
for($i=0; $i<$count; $i++){
$p[]=$this->nodes[$i]->getValue();
}
print_r($this->fPtr->EventHandler);
return call_user_func_array($this->fPtr->EventHandler, $p);
}
}
获取此错误:: call_user_func_array()期望参数1为有效的回调,找不到函数“ mp_div_”或无效的函数名称, 如何调用此功能?类工作创建的魔术方法
