How Can I Permanently Modify Array Values Within a Foreach Loop in PHP?

Modifying Array Values with a Foreach Loop

Problem:

When iterating through an array using a foreach loop, modifications made to array values may not be reflected when converting the array to a string. How can this be resolved?

Solution:

To make modifications to array values permanent within a foreach loop, the trick lies in altering the actual memory location of the values. There are two approaches to achieve this:

1. Memory Reference:

By prefixing the loop variable with an ampersand (&), you create a reference to the original array element:

foreach ($bizaddarray as &$value) {
    $value = strip_tags(ucwords(strtolower($value)));
}

This way, any changes made to $value within the loop are directly reflected in the original array. Remember to unset the variable after the loop to break the reference.

2. Source Array:

Alternatively, you can directly access the source array using an index loop:

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

Here, the $key variable allows you to manipulate the corresponding element within the original $bizaddarray. Either of these methods will securely modify the array's values, ensuring that the HTML tags are removed permanently upon converting the array to a string.
