Array info dissapears when using functions and ob_start

[guarriman]

Hi.

I created these PHP scripts, in order to execute 'foo.php' by using 'ob_start' via another script ('admin.php').

'foo.php' requires some libraries ('functions_for_foo.php' where some arrays are handled) and 'admin.php' requires other libraries ('functions_for_admin.php').

array_info.php

$myList = array ("John", "Mary");

foo.php

require_once("array_info.php");
require_once("functions_for_foo.php");
manageArray();

functions_for_foo.php

function manageArray()
{
	global $myList;
	print_r($myList);
}

admin.php

// OPTION 1
// require_once("functions_for_admin.php");
// doInclude();
// END OPTION 1


// OPTION 2
ob_start();
chdir('/usr/local/httpd/htdocs/');
include('/usr/local/httpd/htdocs/foo.php');
$out = ob_get_contents();
ob_end_clean();

print "<li>GOT CONTENTS:\n";
print $out;
// END OPTION 2

functions_for_admin.php

function doInclude()
{
	ob_start();
	chdir('/usr/local/httpd/htdocs/');
	include('/usr/local/httpd/htdocs/foo.php');
	$out = ob_get_contents();
	ob_end_clean();

print "<li>GOT CONTENTS:\n";
print $out;
}

If I execute 'admin.php' with 'OPTION 2' (without calling 'functions_for_admin.php'), I can display info ($out) from array, but I use 'OPTION 1' (calling 'functions_for_admin.php'), this info dissapears.

Just the same if I don't call 'functions_for_foo.php' within 'foo.php' (got array info if I don't call functions).

Any similar experience?

Thank you very much.

Its only natural that $myList is not known inside the doInclude function. You have to set the global also inside there:

function doInclude()
{
	global $myList;
...

Functions inside functions dont know of eachothers variables unless you assign them global inside the first function also.
