remove row from array

helz

lets say i want to use:
extract($_POST);

eg:

$_POST = "field1 => value1
field2 => value2
field3 => value3";

how can i delete one of the rows when given the correct field name?

so if i wanted to delete field2, it would leave:
$_POST = "field1 => value1
field3 => value3";

if this is possible using a simple string, could it be possible to use an array so that both the array and the $POST can be cross-referenced and where there are the same fieldname in both it deletes it from the $POST array?

unset($_POST['value2']);
is that what you mean?

helz

yup, now could i make that so instead of having an unset() per variable, could i use it in an array so all i need to do is add fieldnames into the array to delete it from $_POST?

bubblenut

<?php
for($i=0;$i<count($bad_vars);$i++) {
  unset($_POST[$bad_vars[$i]]);
}
?>

Like that?

yup, so to create the array, all i need is this hardwired into the code:

$bad_vars = array("var1, var2, var3");
