How to Remove an Array Element While Iterating with `foreach` in PHP?

Removing an Array Element within a Foreach Loop

When looping through an array using foreach, there may arise the need to remove specific elements that meet a certain condition. Consider the following scenario where you want to loop through an array while checking for a particular value. If found, you need to eliminate the corresponding element.

Code Example:

foreach($display_related_tags as $tag_name) {
    if($tag_name == $found_tag['name']) {
        // Delete element
    }
}

The question lies in how to remove the element once the value is found. By incorporating the key into the loop, you can access and remove the element seamlessly.

Solution:

foreach ($display_related_tags as $key => $tag_name) {
    if($tag_name == $found_tag['name']) {
        unset($display_related_tags[$key]);
    }
}

Using the unset function with the key of the matching element, you can effectively remove it from the array. This method allows you to modify the original array while iterating through it, providing a concise and efficient way to remove elements based on specific conditions.
