What are some best practices for processing a comma-separated list with over 100 entries in PHP?

When processing a comma-separated list with over 100 entries in PHP, it is best to split the list into an array using the `explode()` function and then iterate over the array to perform any necessary operations. This approach helps to avoid memory issues that may arise from processing a large list as a single string. 

// Sample comma-separated list with over 100 entries
$list = "entry1, entry2, entry3, ...";

// Split the list into an array
$entries = explode(", ", $list);

// Iterate over the array to process each entry
foreach ($entries as $entry) {
    // Perform operations on each entry
    echo $entry . "<br>";
}
