array - PHP code example

PHP Function Array

PHP array function are a set of functions that allow you to manipulate and work with arrays in the language. These include sorting, searching, filtering and transforming the array elements. These are a set of essential functions that every developer should know and use.

Sorts an array by keys and values using a user-defined comparison function. The first element in the array is removed and replaced with a new value at index one greater than its previous position. The new value is then inserted into the end of the array. This function is the opposite of array_pop().

A simple way to convert a string into an array in PHP is by passing it to the explode() function, which splits the string into an array of elements based on a separator. This is not to be confused with the deprecated split function, which used to be used to create an array based on a single value.

Changing the key of an array element is done by calling the unset() function on the specific element. You can also use the shorthand notation that was introduced starting in PHP 5.4, which uses square brackets instead of curly braces to access elements.

The each() function is a great tool for traversing an array, as it returns the current key and value pair from the current position in the array. However, if you try to use a key that is not an integer or a valid string representation of an integer, it will trigger a TypeError exception and return the next element in the array instead.
