php錯誤提示:Call-time pass-by-reference has been deprecated_PHP教程

今天在寫引用時突然出現了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錯誤，後來才知道原因是此方法已不被贊成並在 PHP/Zend 未來的版本中很可能不再支援了

解決辦法

第一種方法、 把php.ini的display_errors = on改成display_errors = off (不顯示錯誤)

第二種方法、allow_call_time_pass_reference = Off 變成 allow_call_time_pass_reference = On

上面是對php.ini進行修改，但是如果你沒有許可權可以修改程式，下面我舉個簡單的例子

可能出現問題的

代碼如下	複製代碼
function test1($a,$b){ $b = "fun_test1"; return; } $a = "a_value"; $b = "b_value"; test1($a,&$b);

不會有問題出現

代碼如下	複製代碼
function test2($a,&$b){ $b = "fun_test2"; return; } $a = "a_value"; $b = "b_value"; test2($a,$b);
