Strange! No warning for missing argument?

[reefat]

I have been scripting (some may say programming) in PHP for last 5 years but never faced this issue. Interesting!

 

Say for example, I created a custom function with one argument:

 

function myFunc($arg1) {
echo $arg1;
}

 

Now, if I call this function without supplying any argument it doesn't give any error/warning. Any other high level language like C++ or Java would produce error in this case. So, I had to modify my code as follows:

 

function myFunc($arg1) {
if (!isset($arg1)) {
	echo "Missing argument 1";
}
echo $s;
}

 

But this is annoying. Now I have to add these EXTRA lines of code in every function and class methods I have created. Is there any shortcut/easy method that the script will always produce an error if its missing any required argument? I have tried with adding error_reporting(E_ALL); at the very beginning of my code. But it still didn't work out. By the way, I am using PHP 5.3.1 on Apache/2.2.14 (Unix).

 

Any suggestion will be appreciated.

It generates a missing argument warning for me on 5.2.14. I haven't installed 5.3.x yet, so I can't check it on that . . .

Do you have display_errors set to ON as well?

Generates missing argument warning in PHP 5.3.2 here.

Oops! Forgot to mention that I'm using a custom error handler set by set_error_handler("__error_handler"); . E_COMPILE_WARNING was turned off there. This was causing the problem. Sorry for the confusion. And thanks a lot for the cooperation.

PHP, like Perl, has a "no complaints mode."  Use this line to turn error-reporting on:

error_reporting(E_ALL);

Put that at the top of your script, or edit your PHP.ini file, and you'll see all the errors you've been missing.

 

Also, as a side note, it's possible to make a function argument optional in PHP by supplying it with a default value:

function myFunc ( $a = "Hello, World!" ) {}
