Course Introduction:Methods to maintain key-value correspondence after PHP array deduplication include: use the array_unique() function to remove duplicate values, and then use the array_flip() function to exchange key-value pairs. Merge the original array with the deduplicated array, and use the array merging method to retain key-value correspondence.

Course Introduction:In PHP, use the array_unique() function to remove duplicates from an array based on specific key-value pairs. When calling the function, pass in the array as a parameter and select the sorting method as the second parameter. This function returns a new array in which duplicates have been removed based on the specified key-value pairs.

Course Introduction:To remove duplicate elements in a multidimensional PHP array, you can use the array_unique() function or a custom recursive function. array_unique() will process the internal array as a whole, while the custom recursive function will iterate over the array and examine them element by element. In a practical use case, these methods can be used to remove duplicate email addresses to ensure that only one email is sent to each user.

Course Introduction:How to remove duplicate values from PHP array using regular expressions: Use regular expression /(.*)(.+)/i to match and replace duplicates. Iterate through the array elements and check for matches using preg_match. If it matches, skip the value; otherwise, add it to a new array with no duplicate values.
