This example comes in handy when you need to get a full list of all current state global variables anywhere in your script. The lists will be printed with code highlighting for easy viewing:). Useful for debugging in your browser.
The function simply dumps out a list of $_POST, &_GET, $_SESSION, $_REQUEST, $_COOKIE, $_ENV and $_FILE if available.
Just call <? echo dump_vars(); die; ?> anywhere in your code that you want the current variable state dumped.
There are many better solutions to help with debugging, but this is a quick way to get an applications current state.
This could be adapted to support 3d arrays also!!
| <?php
function f_arr($arr) {
$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 => $fe";
if(is_array($arr)) {
foreach($arr as $k=>$v){
$out[] = $l.$fb.$k.$fe.$r.$a.$fr.$v.$fe;
}
}
if(is_array($out)) {
return implode("<br />", $out);
} else {
return false;
}
}
function dump_vars() {
$out = "";
if($a = f_arr($_SESSION)) {
$out .= "SESSION[] ( <br><blockquote> $a </blockquote>) <br>";
}
if($a = f_arr($_REQUEST)) {
$out .= "REQUEST[] ( <br><blockquote> $a </blockquote>) <br>";
}
if($a = f_arr($_POST)) {
$out .= "POST[] ( <br><blockquote> $a </blockquote>)
<br>";
}
if($a = f_arr($_GET)) {
$out .= "GET[] (<br><blockquote> $a </blockquote>)<br>";
}
if($a = f_arr($_COOKIE)) {
$out .= "COOKIE[] (<br><blockquote> $a </blockquote>)
<br>";
}
if($a = f_arr($_ENV)) {
$out .= "ENV[] (<br><blockquote> $a </blockquote>)<br>";
}
if($a = f_arr($_FILES)) {
$out .= "FILES[] (<br><blockquote> $a </blockquote>)
<br>";
}
return $out;
}
