php错误提示:Call-time pass-by-reference has been deprecated_PHP教程

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 复制代码

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 复制代码

function test2($a,&$b){

$b = "fun_test2";

return;

}

$a = "a_value";

$b = "b_value";

test2($a,$b);
