foreach ($array_leave_dates as $emp => $leave_type) {
foreach ($leave_type as $leave_dates) {

Here we can fetch $leave_dates and want to remove or unset leave_type == 'Maternity Leave'. But could'nt. Please help to point out the mistake in my code above.
Have a look at the // comments
foreach ($array_leave_dates as $emp => $leave_type) {
// you treat $leave_type as array here
foreach ($leave_type as $leave_dates) {
// you treat $leave_type as string here
// doesn't feel right
if($leave_type == 'Maternity Leave') {
// you are unsetting with a value
//unset($array_leave_dates[ --> $leave_type <-- ]);
// i assume you want to delete the key
unset($array_leave_dates[$emp]);
}
else{
// $row doesn't seem to exist, looks wrong from here
echo $leave_dates[$row];
}
}
}
Not sure what your data source looks like:
<?php
// Remove the whole employee
$employees = array(
'emp1' => array('sick' => 'Mon - Tue'),
'emp2' => array('bun in oven' => '2016 - 2017'),
'emp3' => array('broken heart' => '2017 - ∞'),
);
foreach ($employees as $emp => $leave) {
foreach ($leave as $leaveName => $date) {
if($leaveName == 'bun in oven') {
unset($employees[$emp]);
}
}
}
print_r($employees);
// OR remove only 'Maternity' from the employee but keep everything else
<?php
$employees = array(
'emp1' => array('sick' => 'Mon - Tue', 'its friday and im not coming in' => 'Fri'),
'emp2' => array('bun in oven' => '2016 - 2017', 'sick' => 'Thu'),
'emp3' => array('broken heart' => '2017 - ∞'),
);
foreach ($employees as $emp => $leave) {
foreach ($leave as $leaveName => $date) {
if($leaveName == 'bun in oven') {
unset($employees[$emp][$leaveName]);
}
}
}
print_r($employees);
If $leave_type can be "Maternity Leave", then why do you search for $leave_dates inside that string value? The question is naturally rethorical. From the very fact that you have two foreach cycles and the second is embedded into the first makes me think that $leave_type is not what you think it is. So, I think you have a multi dimensional array, where the outer keys are employee names or ids and the inner keys are the types. Example:
array(
'John Doe' => array('Sickness' => array('a', 'b', 'c')),
'Mary Doe' => array('Sickness' => array('a', 'b', 'c'), 'Maternal Leave' => array('d', 'e'))
)
If that is the case, then you need to modify your cycles:
foreach ($array_leave_dates as $emp => $leave) {
if ($leave['Maternity Leave']) {
unset($array_leave_dates[$emp]['Maternity Leave']);
}
}
If you want a more general solution, then this might help you:
function removeByKey(&$arr, $k) {
if (arr[$k] !== null) {
unset arr[$k];
}
foreach($arr as $key => $value) {
if (is_array($value)) {
$arr[$key] = removeByKey($arr[$key], $k);
}
}
return $arr;
}
