Weird problem with variables

[Anon]

here is my code:

some html

<?php
$fooArray = array("foo", "bar");

  function prntFoo(){
    foreach($fooArray as $value){
       print($value);
    }

?>

some html code

<?php prntFoo() ?>

more html code

ok now the problem is I get an error that
$fooArray is undefined. What could be the problem?

thanks!

Try $GLOBALS("fooArray")

or pass the array as a argument to the function

As Ellery suggests, it's better to pass the var to the function than to use globals.

<?php
$fooArray = array("foo", "bar");
prntFoo($fooArray);

function prntFoo($paTheArray)
{
foreach($paTheArray as $value){
print($value);
}
?>

or put an

global $fooArray;

in your function!

thanks for your help, is there any reason why
php functions do not see global variables without using global?

Read the manual:
http://www.php.net/manual/en/language.variables.scope.php

While there are superficial similarities in the languages, variable scoping in PHP does not work like variable scoping in C.

The historical reason is this: Originally, all PHP variables were globally visible. One day Rasmus Lerdorf got bit by a namespace collision one time too many, and arbitrarily decided that functions could not "see" variables that were not specifically imported (declared).
