How Can I Permanently Remove HTML Tags from Array Elements in a PHP foreach Loop?

Modifying Array Values using a foreach Loop

In a situation where you want to modify array elements based on specific operations, using a foreach loop provides a straightforward approach. However, if these modifications involve HTML tag removal and you intend to convert the array into a string later, you may encounter issues where the tags remain intact.

To address this challenge and make the HTML tag removal permanent, you have two options: modifying the original array elements by memory reference or accessing them through the source array.

Method 1: Memory Reference

By accessing each element with a reference (using '&'), you can directly modify its contents. This ensures that the updates made within the loop are saved to the original array.

foreach ($bizaddarray as &$value) {
    $value = strip_tags(ucwords(strtolower($value)));
}
unset($value); // Remove the reference after the loop

Method 2: Source Array

Alternatively, you can access the array elements through the source array. This approach involves assigning the modified value to the corresponding key in the original array.

foreach ($bizaddarray as $key => $value) {
    $bizaddarray[$key] = strip_tags(ucwords(strtolower($value)));
}

Both methods will permanently remove the HTML tags from the array elements, allowing you to convert the array to a string without any residual HTML markup.
