writing my own var_dump()

traveller

Hi,

I want to write a function which is almost the same as var_dump(). Here is what I want to do. I want to print out all the values of an array, in the way var_dump does it. That works fine for me, until I use multi-dimensional arrays. When I have a multi-dimensional array I'd like to have my output indented en that's my problem.

This is my function:
<?
function dumparr($arr){
if(is_array($arr)){
$elements = count($arr);
echo "Array[$elements] { ";
for($i=0;$i<$elements;$i++){
if(is_array($arr[$i])){
dumparr($arr[$i]);
} else {
echo "   [$i] => " . htmlentities($arr[$i]) . " ";
}
}
echo "} ";
} else {
echo "not an array ";
}
}

and this is my test array:

$an_array = array(
array("this", "is", "a"),
array("multi", "-", "dimensional"),
array("array", ".", "the"),
array("output", "is", "wrong"));

dumparr($an_array);

I'd be very thankfull for those who help me out!

try with print_r($a_variable);

you need PHP4

I know, but I want to write it myself.
So, any other ideas??

check this:
<?
function debugEchoArray($anArray,$levelNumber){
if (!$levelNumber) echo "<TABLE BORDER=1>";
if (gettype($anArray) != 'array'){
echo "<TD>".$anArray."</TD></TR>\n";
return;
};
foreach($anArray as $key=>$value){
echo "<TR>";
for ($i=0;$i<$levelNumber;$i++) echo "<TD></TD>";
echo "<TD>".$key."</TD>";
debugEchoArray($anArray["$key"],$levelNumber+1);
};
if (!$levelNumber) echo "</TABLE>";

}

function debugEcho($aString){

    if (gettype($aString) == "array" ){
            debugEchoArray($aString,0);
            return;
    }
    echo "<TABLE ><TR><TD>".$aString."</TD></TR></TABLE>";

}

$x=array( a=> array ('a1','a2','a3'),
b=> array ('b1', b_array => array('b_a1', 'b_a2')),
c => 'c_val');
debugEcho($x);
?>

Thank you! That works fine.
