Check if value exists within an array of objects - php

Question

I am working on an API which receives a PHP object of $POST data. I am trying to check wether the 'smsPhoneNumber' inside customFields exists but not sure how to do this.
I am currently able to check for 'email' using:
if ( property_exists( $data, 'email' ) ) {
return true;
}
Question: How to check if 'smsPhoneNumber' exists?

var_dump:
object(stdClass)[1515]
public 'email' => string 'email#email.com'
public 'customFields' =>
array (size=2)
0 =>
object(stdClass)[1512]
public 'name' => string 'Firstname'
public 'value' => string 'james'
1 =>
object(stdClass)[1514]
public 'name' => string 'smsPhoneNumber'
public 'value' => string '077'

Answer 1

You could use an array_filter to get the custom field you want.
$phoneFields = array_filter($data->customFields, function($field) {
return $field->name === 'smsPhoneNumber';
});
This will only return objects in the array that have a name property equal to smsPhoneNumber.
if (!count($phoneFields)) {
// Phone not found
}
// or
if ($phone = current($phoneFields)) {
echo "The first phone number found is " . $phone->value;
}

The drawback of using array_filter() to search for the subarray values is:
array_filter() will not stop once it finds a match; it will keep iterating even after a match is found until it reaches the end of the array.
You should use a technique that allows an early break/return.
I recommend a simple foreach() with a break.
$foundIndex = null;
foreach ($data->customFields as $index => $customFields) {
if ($customFields->name === 'smsPhoneNumber') {
$foundIndex = $index;
// or $wasFound = true;
// or $smsNumber = $customFields->value;
break;
}
}
This will prove to be very efficient and easy to read/maintain.
