Php error message: Call-timepass-by-referencehasbeendeprecated

Today, when writing a reference, the following error occurs: Warning: Call-timepass-by-referencehasbeendeprecated-argumentpassedbyvalue; Ifyouw.

Today, when writing a reference, the following error occurs: Warning: Call-time pass-by-reference has been deprecated-argument passed by value; If you wocould like to pass it by reference, modify the declaration of getimagesize (). if you wowould 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 error. later I learned that this method was no longer supported and may not be supported in future PHP/Zend versions.

Solution

First, change display_errors = on of php. ini to display_errors = off (no error is displayed)

Method 2: convert allow_call_time_pass_reference = Off to allow_call_time_pass_reference = On

The above is to modify php. ini, but if you do not have the permission to modify the program, the following is a simple example. the code that may cause problems is as follows:

1. Function test1 ($ a, $ B ){
2. $ B = "fun_test1 ";
3. Return;
4. }
5. $ A = "a_value ";
6. $ B = "B _value ";
7. Test1 ($ a, & $ B );

The code is as follows:

1. Function test2 ($ a, & $ B ){
2. $ B = "fun_test2 ";
3. Return;
4. }
5. $ A = "a_value ";
6. $ B = "B _value ";
7. Test2 ($ a, $ B );
