The array_flip() function exchanges all keys with their associated values in an array. It returns flipped array on success, else NULL on failure. Syntax array_flip(arr) Parameters arr − Specify the array of key/value pairs to be flipped. Return The array_flip() function returns flipped array on success, else NULL on failure. Example Live Demo Output Array ( [keyboard] => p [mouse] => q [monitor] => r )

The array_filter() function filters elements of an array using a user-made callback function. It returns the filtered array.Syntaxarray_filter(arr, callback, flag)Parametersarr − The array that will be filteredcallback − The callback function to be usedflag − The parameters sent to the callback function:ARRAY_FILTER_USE_KEY − pass key as the only argument to callback instead of the valueARRAY_FILTER_USE_BOTH − pass both value and key as arguments to callback instead of the valueReturnThe array_filter() function returns the filtered array.Example Live DemoOutputArray ( [1] => 6 [4] => 20 [5] => 30 [7] => 48 [9] => 66 )
