PHP 5.4 Call-time pass-by-reference - Easy Fix Available

PHP 5.4 Call-time pass-by-reference - Easy fix available?

You should be denoting the call by reference in the function definition, not the actual call. Since PHP started showing the deprecation errors in version 5.3, I would say it would be a good idea to rewrite the code.

From the documentation:

There is no reference sign on a function call - only on function definitions. Function definitions alone are enough to correctly pass the argument by reference. As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use & in foo(&$a);.

For example, instead of using:

// Wrong way!
myFunc(&$arg);               # Deprecated pass-by-reference argument
function myFunc($arg) { }

Use:

// Right way!
myFunc($var);                # pass-by-value argument
function myFunc(&$arg) { }

PHP 5.4 Call-time pass-by-reference - Easy fix here?

Just remove the leading & like this:

$fp = fsockopen($url['host'], "80", $errno, $errstr, $timeout);

the variables are still passed by reference, but you don't need the & to indicate that from PHP 5.4 onwards.

PHP Fatal error: Call-time pass-by-reference has been removed

You are supposed to specify the requirement for a reference when the function is defined, not when you call the function.

So amend the function call to

fsockopen("$scip", $scport, $errno, $errstr, 30);

If the function has been defined as requiring a reference it will turn your call time parameters into references and if it does not require a reference it will not

PHP Fatal error: Call-time pass-by-reference has been removed

You are trying to pass a pointer to your array in array_push. That is why the fatal error is encountered. Simply use:

array_push( $image_set, $images[fname] );

Note: array_push() will raise a warning if the first argument is not
an array.

PHP 5.4 Call-time pass-by-reference has been removed - way to ignore?

A fatal error cannot be stopped (this is why they are called fatal) - not even by stuff like set_error_handler.

You will have to change your code.

But fixing it should not be a huge problem, because the error is caused by & in function calls:

function test($param) { }
test(&$test);      // fatal error

function test(&$param) { }
test($test);       // no error

Documentation:

• As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use & in foo(&$a);.
• And as of PHP 5.4.0, call-time pass-by-reference was removed, so using it will raise a fatal error.

So to make a (very) nasty workaround, you could install PHP 5.3.0 :(

Call-time pass-by-reference has been removed

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

PHP call-time pass-by-reference

This error happens because of &$in function call which is deprecated, remove & and your code should work.
Meaning that you should change:

Pasw13_MeseAnnoCorrenti(&$Anno,&$Mese);

to

Pasw13_MeseAnnoCorrenti($Anno,$Mese);

Call-time pass-by-reference has been deprecated

Remove the & before $this.

PHP5 doesn't need that added - all objects are passed as object identifiers by default, no need to mimic this with passing by reference as it was required for PHP 4.
