今天在写引用时突然出现了Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference,modify the declaration of getimagesize(). If you would like to enable call-time pass-by-reference,you can set allow_call_time_pass_reference to true in your INI file. However,future versions may not support this any longer错误，后来才知道原因是此方法已不被赞成并在 PHP/Zend 未来的版本中很可能不再支持了

解决办法

第一种方法、把php.ini的display_errors = on改成display_errors = off (不显示错误)

第二种方法、allow_call_time_pass_reference = Off 变成 allow_call_time_pass_reference = On

上面是对php.ini进行修改，但是如果你没有权限可以修改程序，下面我举个简单的例子,可能出现问题的代码如下:

function test1($a,$b){
$b = "fun_test1";
return;
}
$a = "a_value";
$b = "b_value";
test1($a,&$b);

不会有问题出现代码如下:

function test2($a,&$b){
$b = "fun_test2";
return;
}
$a = "a_value";
$b = "b_value";
test2($a,$b);
