I an looking to search an array based on a nested arrays value. My Array looks like this.
$arr = array(100 => array('fname' => 'John',
'lname' => 'Smith',
'phone' => '18005551212'),
555 => array('fname' => 'Michael',
'lname' => 'Gold',
'phone' => '18005550000')
)
I know I can use $arr[100] to get the values there. How would I go about searching for the value where say their phone number is 18005551212 and then find the array key based on that? Is the only option to have a for each and loop through the entire array every time?
