functions... within functions?

[Anon]

Ok, I am trying to call a function within another function. However, the variables I set within the second function don't return to the first one when it comes back (ends the second function). I tried global, but it didn't seem to carry it over. Also, I am trying to carry an array back from function 2 into function 1, but when I count it, it comes back as 0. Thanks

uhm tried with reference?

func foo()
{
$aRey=array();
foo2($aRey);
}

func foo2(&$ar)
{
array_push($ar,"uops");
}

For debugging purposes, try using [ var_dump($your_var_name); ]
to check the contents of your variable just before you [ return $your_var_name; ].

Then try var_dump in the calling function. If they report the same, then it's not an issue with returning data. Make sure you are using "return" appropriately.

I do this all the time and have never had a problem.

Good luck,

Here, I'll just insert the code..

It's called from temp.php
like:

build_menu_system("shot","",$menu_style);

---

Menu System

function build_menu_system($menu_selection, $item_checked, $menu_style)
{

build_file_connection("menu/$menu_selection.menu");

echo "<select name=\"$menu_selection\" $menu_style> \n\n";

for($num = 0; $num < count($file_array); $num++)
	{

	##### Split the entrys #####
	$database_entry = explode("|",$file_array[$num]);

	print("crap | $database_entry[0], $database_entry[1] count($file_array)");

	##### Now, check for types of selections in menu #####
	if($database_entry[0]) { echo "<option name=\"null\" value=\"null\" title=\"$database_entry[1]\">-->$database_entry[1]"; }

	if($database_entry[0] == "") { echo "<option name=\"$database_entry[1]\" value=\"$database_entry[1]\" title=\"$database_entry[1]\">"; }

	} /* end for */  

echo "</select>\n\n";


} /* end function */

File Connection

function build_file_connection($file_name)
{
global $file_opened;
global $file_array;

$file_opened = $file_name;

$file_array = file($file_name);

}

I generally avoid using globals whenever possible. In your function build_file_connection you mentioned $file_opened, but it looks like it is only used in this function. And you don't really even need it. In fact, if you remove that, your function is reduced to [ $file_array = file($file_name); ]. I wouldn't even bother using this build_file_connection function. Just use the $file_array = file(file_name) in your build_menu_system.

But assuming that you have a good reason for doing it that way, I would not declare those as globals. At the end of build_file_connection, add this line:

return $file_array;

Then in build_menu_system, do this:
$your_data = build_file_connection($whatever);

Hope this helps,

It works. I love you.

Yes, I do have good reason. I have tons of menus, and they are always changing. I want to make it easy to change them. Also, the $file_opened has to do with something else in the script altogeather. But thanks a ton!
