Today, when the cici user sent a question saying that the error suppression symbol (@) was used before the function call parameter, it seems that the parameter passing through the reference will become invalid. he wanted me to answer why. see the following example:
The code is as follows:
$ Array = array (1, 2, 3 );Function add ( $ arr ){$ Arr [] = 4;}Add (@ $ array );Print_r ($ array );/**At this time, $ array does not change and the output is:Array([0] => 1[1] => 2[2] => 3)*/Add ($ array
See the following example:
Copy codeThe Code is as follows: $ Array = array (1, 2, 3 );
Function add ( $ arr ){
$ Arr [] = 4;
}
Add (@ $ array );
Print_r ($ array );
/**
At this time, $ array does not change and the output is:
Array
(
[0] => 1
[1] => 2
[2] => 3
)
*/
Add ($ array );
Print_r ($ array );
/**
