PHP Array - What is an Array?
What is an Array?
An array is a special variable, which can hold more than one value at a time.
For example: if you have a list of items (mobile phone name), storing the mobile phone in single variables could look like this:
$mobile-phone1 = "iPhone";
$mobile-phone2 = "Samsung";
$mobile-phone3 = "Nokia";
$mobile-phone4 = "LG";
However, what if you want to loop through the mobile-phone and find a specific one? And what if you had not 4 mobile-phone, but 250?
Solution is to create an array
An array can hold many values under a single name, and you can access the values by referring to an index number.
