Adding new elements at the beginning of the existing array can be done by using the Array unshift() method. This method is similar to push() method but it adds an element at the beginning of the array.
The unshift() method adds one or more elements to the beginning of an array and returns the new length of the array.
How do you push values in an empty array? Answer: Use the array_push() Function You can simply use the array_push() function to add new elements or values to an empty PHP array.
The push() method is similar to the unshift() method as it adds an element to the end of an array rather than the beginning. It returns the length of the new array and, like the unshift() method, can be used to add more than one element.
You could even, through the power of expressions, do this with a one-liner.
(MyArray[StringVariableName][StringVariableName2] || (MyArray[StringVariableName][StringVariableName2] = [])).push("whatever");
