this is my multidimensional
Now i want to initially check array contains [required] => 1 or [required] => 0
i don't want to traversing array
Let's say your array name is $myarray
So you can do something like this -
foreach($myarray as $arrelement)
{
if(isset($arrelement[required]) && $arrelement[required] == 1) //choose 1 or 0 in code as per your need
{
//traverse your array and do needful
}
}
if($yourArr[0]['required']==0) //Just check for first element in your array
echo "Zero";
else
echo "One";
foreach($mainarray as $array ){ //check for each
if($array['required']==1)
//doSome Task
if($array['required']==0)
This is probably the most hackish solution I'll come up with all this morning, but if you are shooting for a quick one-liner, this should do:
if(in_array(1, array_column($myArray, 'required')))
echo 'required';
Edit: This assumes you've got PHP 5.5+ at hand
Update: After a closer look at the documentation of in_array()
, this should be possible:
if(in_array(array('required' => 1), $myArray))
echo 'required';
As an alternative, my way independent of the array structure (assume $x holds your data structure):
if (preg_match('/"required":[01]/',json_encode($x))) {
// The array structure contains "required" => 0 or "required" => 1
} else {
// Negative
}
