can't return value in function();

[Anon]

Say I have a function that return a value

<?

function bla($id) {

processing....

return $NewId;
}

?>

Then I call the function in other page

bla($id="34");
echo $NewId;

...it never return anything....
Any work arund ?

[brandonschnell]

needs to be:
$NewId = bla($id);
echo $NewId;

don't forget about the scope of variables within functions

[mithril]

Functions in PHP, just as in any programming language, have to return the value into a variable (or print statment or function pass argument, etc.). $NewId does not enter the global scope because you return it...... returns and globals are 2 very different things. Also, you can't put a variable value assignment statement in a function pass. The following will work

&nbsp;&nbsp;echo bla(34);

or

&nbsp;&nbsp;$someVar = bla(34);
&nbsp;&nbsp;echo $someVar;
