[SOLVED] how to calculate the current size of an array post?

[ali_2kool2002]

ie can anyone tel me if there is a function i could use or something to find the current size of this array?

 

$_POST['txtbox']

 

i want to know the current size, which im not sure what it is  :-\ :-\

do you mean size as in bytes, or size as in number of array indices with values? if you want number of indices:

<?php
        if(isset($_POST)){
                echo "Number of Indices: ". count($_POST) ."<br />\n";
        }
?>

 

or try:

<?php
        if(isset($_POST)){
                $i = 0;
                foreach($_POST as $key => $val){
                        if ($val != "") { $i++; }
                }
        echo "Number of Indices: ". $i ."<br />\n";
?>

 

try them both and see if your results differ for each piece of code.

get more info from the count() manual page.
