I wish to iterate through a multidimensional array and remove arrays that have "approved" set to zero. I have tried using the unset
method as suggested in other stackoverflow threads, but to no avail. I have also tried to reindex the array as per this stackoverflow link .
foreach ($dentists as $key => $dentists_index)
{
if($dentists_index["approved"] == 0)
{
unset($dentists[$key]);
}
}
Any help would be greatly appreciated.
Actually your code looks correct! Check out this quick test that worked well and outputs a line to debug each dentist:
<?
$dentists = array(
array(
'name' => 'kevin',
'approved' => 0,
),
array(
'name' => 'cathy',
'approved' => 0,
),
array(
'name' => 'steven',
'approved' => 1,
),
);
foreach ($dentists as $key => $dentists_index) {
print "Dentist #$key - Approved: " . $dentists_index['approved'] . "<br />\n";
if($dentists_index['approved'] == 0) {
unset($dentists[$key]);
}
}
var_dump($dentists);
?>
