What exactly is it for? Could you just use an array like '$page_vars' or something?

You should look at the function get_defined_vars()

will do

ok,

 

ive done that

 

when it comes to echoing the database link stuff, it says that mysqli_object cannot be converted to string, so how do i catch that error and replase it with the string eg "MYSQL OBJECT"

 

this is what i have:

 

 

$page_variables = get_defined_vars();

foreach($page_variables as $field1 => $value1) {
if(is_array($array1)) {
	foreach($field1 as $field2 => $value2) {
		echo $field2." => ".$value2."<br>";
	}
}
else{
	echo $field1." => ".$value1."<br>";
}

}

 

i only have variables and arrays, from memory no multidimentional arrays....... but i know that ive got for example a loop that loops througha mysql result, and there are many records int he result, so i used the while(var = mysqli_fetch_array) so how do i get those values ( if i cant thats ok)

 

thankx

If you just want to see what's in the array, you can do:

<?php
$page_variables = get_defined_vars();
echo '<pre>' . print_r($page_variables,true) . '</pre>';
?>
