Php – Associative array with multiple values in php

arraysphp

can we have associative array with multiple values for same key in php ?

example:-

array[key1] => value1, value2, value3
array[key2] => value4, value5, value6

Yes:

array[key1] => array(value1, value2, value3)
array[key2] => array(value4, value5, value6)

You can also have associative arrays in an associative array:

array[key1] => array(key => value1, key => value2, key => value3)
array[key2] => array(key => value4, key => value5, key => value6)

new ArrayList<>(Arrays.asList(array));

Modern browsers have Array#includes, which does exactly that and is widely supported by everyone except IE:

console.log(['joe', 'jane', 'mary'].includes('jane')); //true

You can also use Array#indexOf, which is less direct, but doesn't require polyfills for outdated browsers.

console.log(['joe', 'jane', 'mary'].indexOf('jane') >= 0); //true

Many frameworks also offer similar methods:

Notice that some frameworks implement this as a function, while others add the function to the array prototype.
