There are three types of array in PHP:
- Indexed array: an array with a numeric key.
- Associative array: an array where each key has its specific value.
- Multidimensional array: an array containing one or more arrays within itself.
In PHP, there are three main types of arrays:
- Indexed arrays: These are arrays where each element is assigned a numeric index starting from 0.
Example:
php
$indexedArray = array("apple", "banana", "orange");
- Associative arrays: In associative arrays, elements are assigned a specific key rather than a numeric index. The key-value pairs can be of any data type.
Example:
php
$associativeArray = array("fruit1" => "apple", "fruit2" => "banana", "fruit3" => "orange");
- Multidimensional arrays: These are arrays within arrays. They can be a combination of indexed and associative arrays.
Example:
php
$multiDimensionalArray = array(
array("name" => "John", "age" => 30),
array("name" => "Jane", "age" => 25),
array("name" => "Doe", "age" => 40)
);
When answering in an interview setting, it’s good to mention these three types and perhaps provide a brief example or explanation of each to demonstrate understanding.
