How to Parse Input Arrays from HTML Forms in PHP

When you have a form with multiple fields that share the same name attribute, such as when using jQuery to dynamically add fields, PHP receives the input values as arrays. However, these arrays are raw and not immediately compatible with the structure you desire.

To convert the received data into an array of individual objects, follow these steps:

// Get the input arrays from the form
$name = $_POST['name'];
$email = $_POST['email'];

// Iterate over the input array indexes
foreach ($name as $key => $n) {
  // Each field pair corresponds to an element in each input array
  // Using the same index, extract both name and email values
  $output = "The name is $n and email is $email[$key], thank you";
  
  // Optionally, store the result in an array for further processing
  $results[] = $output;
}

// Display or use the results as needed
print_r($results);

This solution takes advantage of the fact that input arrays maintain the same indexing, allowing for easy pairing of name and email values. By utilizing a foreach loop, you can dynamically generate the desired output.

To handle multiple additional form fields, simply extend the loop structure and include the corresponding array names:

foreach ($name as $key => $n) {
  $output = "The name is $n, email is $email[$key], and location is $location[$key]. Thank you";
  $results[] = $output;
}
