How Can I Efficiently Synchronize Array Iteration in PHP for Selectbox Generation?

Synchronizing Iteration over Arrays of Equal Size for Selectbox Generation

In order to create a selectbox element using PHP, you need two arrays: one with country codes and another with country names. Iterating through these arrays and printing their values simultaneously can be tricky.

Initial Attempt:

One might initially try using the following approach:

foreach( $codes as $code and $names as $name ) {
    echo '<option value="' . $code . '">' . $name . '</option>';
}

However, this syntax is not valid.

Solution:

To solve this issue, you can use the array index as the key for iterating through both arrays:

foreach( $codes as $index => $code ) {
    echo '<option value="' . $code . '">' . $names[$index] . '</option>';
}

Alternative Approach:

Instead of using arrays, you could simplify the code by using a key-value pair instead, with country codes as keys and country names as values:

$names = array(
    'tn' => 'Tunisia',
    'us' => 'United States',
    ...
);

This approach streamlines the iteration process as you can directly access the value associated with each key.
