Data is generally passed in the form of objects or arrays; Mastery of array handling is critical to improving your programming skills.
PHP has a lot of array handlers, but I’ve just picked up a few that have been used frequently in recent projects.
1. In_array () checks whether the specified value exists in the array.
Array_values () returns all the values in the array.
Array_merge () merges one or more arrays into one array.
The array_diff() function returns the number of difference sets between two arrays. This array contains all the keys that are in the array being compared, but not in the parameter array.
Array_push () inserts one or more elements into the end of the array.
Array_map () applies a user-defined function to each value in the array and returns the array with the new value.
Array_column () returns the value of a single column in the input multidimensional array.
Array_search () searches an array for the specified value, returns the key value, and can only match exactly, only one.
Array_chunk () splits an array into new chunks.
Array_combine () creates a new array by combining two arrays, one with key names and the other with key values
