How can htmlentities impact the comparison of strings in PHP when updating database entries?

When updating database entries in PHP, using htmlentities to encode special characters can impact the comparison of strings. This is because htmlentities converts special characters into their HTML entities, which can alter the original string. To solve this issue, before comparing strings in PHP, you should decode the HTML entities back to their original characters using the html_entity_decode function. 

// Example code snippet to update a database entry and compare strings after decoding HTML entities

// Update database entry with htmlentities encoding
$newEntry = htmlentities($newEntry);

// Decode HTML entities before comparison
$originalEntry = html_entity_decode($originalEntry);

// Compare strings after decoding HTML entities
if ($newEntry === $originalEntry) {
    // Strings are equal after decoding HTML entities
    // Perform necessary actions
} else {
    // Strings are not equal
    // Handle the comparison result accordingly
}
