An alternative to print_r, this function will print an array
with HTML and Syntax highlighting. Could easily be extended to
support 3D arrays.
USAGE: echo f_arr($_SESSION);

<?php
function f_arr($arr) {
$fr = "<font color=red size=1>";

$fe = "</font>";
$l = "$fg [ $fe";

single dimension arrays only then.
If you called the function from within itself then it would recurrsively step through it and get the entire contents.
foreach($arr as $k=>$v){
if (isarray($v){
$out[] = "array ".$k."[".f_arr($V)."]";
} else {
$out[] = $l.$fb.$k.$fe.$r.$a.$fr.$v.$fe;
}
}
This method takes longer and more memory than just doing print_r but it gves you the formatting you require.

To finalize a version for printing multi-dimensional arrays you can use something like the following: (formatting may be required)
<?php
// An alternative to print_r, this function will print an array

// support 3D arrays.
// USAGE: echo f_arr($_SESSION);
// Revised for multi-dimensional arrays
// Aaron Holmes <aholmes@pureguru.com>
function f_arr($arr) {
global $v;
$fr = "<font color=red size=1>";
$fg = "<font color=green size=1>";
$fb = "<font color=blue size=1>";
$fk = "<font color=black size=1>";
$fe = "</font>";
$l = "$fg [ $fe";
$r = "$fg ] $fe";
$a = "$fk => $fe";
$out = "";
foreach($arr as $k=>$v) {
if(is_array($v)) {
$out[] = "array ".$k."[".f_arr($v)."]";
} else {
$out[] = $l.$fb.$k.$fe.$r.$a.$fr.$v.$fe;
}
}
if(is_array($out)) {
return implode("<br />", $out);
} else {
return false;
}
}
