Array Functions (PHP)

I will describe some functions, while we can use it in working with Array.

count(x) = If we write a sequence of variable for x, it will count how many element is in this sequence.

For Example:

$a[4]=10;

$number=count($a);

It will show us how many elements is in this ($a) sequence.

array_pop($sequence) = it is take off the last element of $sequence sequence.

For Example:

$a=array('a','b','c');

echo array_pop($a);

//## c will be in output of this code. It will give to us a last element of this sequence.

array_push($sequence,"elements ") = It is using for adding new elements to the end of the sequence.

For Example:

$a=array("a","b","c");

array_push($a,"d","f");

//## This code add ”d” and “f” to the end of the sequence.
