Call=time pass reference QUESTION?

Sorry if this seems like a stupid question but I know absolutely nothing about Php. I have come across the "Call-time pass-by-reference has been deprecated" error many times I find it usually around code that looks like this

$size = getimagesize ($photo,&$info);
if(isset ($info["APP13"]))
{

PHP:

I stop getting the error if I remove the & I don't know if this effects the operations of the script however, it just stops the error. I read somewhere that the "Call-time pass-by-reference has been deprecated" basically means that the code is or will be obsolete or is no longer or will no longer be supported. I also heard that adding the line allow_call_time_pass_reference to my php.ini file will fix this error. So my question is should I delete all the & directly before the $ or add the code to the .ini file. Obviously I would be better off using the corrector newer method of the code but as I said I don't know anything about PHP. Suggestions or help would be much appreciated.

By reference can only be used when defining a function. The & indicates passing by reference.

http://us3.php.net/manual/en/function.getimagesize.php

Referring to there you see that array &$imageinfo is already passed by reference.

Long story short, remove the & sign it is unnecessary.

 

ok Thanks for your help I just wanted to make sure. I will do a search on the files to make sure all the instances of &$ are changed to simply $

 

Make sure that you're not replacing any delcared functions though...

For example, if the code is

$variable = 6;
function myFunction ($variablebyvalue, &$variablebyref) //DO NOT REMOVE THE & HERE
{
$variablebyref = 0;
}
myFunction(1, &$variable); //REMOVE THE & HERE
echo $variable;

PHP:

If you remove the & sign where the function is declared, the script will output 6 instead of 0. The error is being triggered when you place the & where the function is called.

Good luck!
