Working with arrays, including indexed arrays, associative arrays, and multidimensional arrays Mocktest

The output of the code will be Red Green Blue Yellow Orange because the array_push() function is used to add the elements "Yellow" and "Orange" to the end of the $colors array. The foreach loop then iterates over the array, printing each color, resulting in the output Red Green Blue Yellow Orange.

The pop() function in PHP is used to remove the last element from an array and return it.

The output of the code will be 10 20 30 40 because the array_pop() function removes the last element (50) from the $numbers array. The foreach loop then iterates over the modified array, printing each remaining number, resulting in the output 10 20 30 40.

The array_merge() function in PHP is used to merge two or more arrays into a single array.

The output of the code will be a b c 1 2 3 because the array_merge() function merges the elements of $arr1 and $arr2 into a single array $result. The foreach loop then iterates over the merged array, printing each item, resulting in the output a b c 1 2 3.

The correct way to access the first element of an indexed array in PHP is $array[0], as indexed arrays use numerical indices starting from zero to access elements.

The output of the code will be 2 because the count() function in PHP returns the number of elements in an array. In this case, the $info array contains two elements ("name" and "age"), so count($info) will return 2.

The slice() function in PHP is used to extract a slice of an array, creating a new array containing the specified range of elements.

The output of the code will be 30 40 50 because the array_slice() function extracts a slice of the array $arr starting from the element at index 2 (30) to the end, creating a new array $slice. The foreach loop then iterates over the sliced array, printing each item, resulting in the output 30 40 50.

The asort() function in PHP is used to sort an associative array in ascending order while maintaining the key-value pairs intact.
