Arrays are used in any programming language. You can imagine an array as a long box with many the same compartments, like this |___|___|___|___|___|.What ever you put in a compartment is its value. The following array |_a_|_b_|_c_|_d_|_e_| contains characters a,b,c,d,e. To access a value you should know in which compartment it is placed. For example ‘b’ is in the second compartment. In most computer languages array index (counting) starts from 0, not from 1. Index of the first element of the array is 0, Index of the second element of the array is 1 and so on. In array of names below you can see indexes and values.To display “Anna” array value you have to access element (compartement) with index 3. print($names[3]); To display all array values – use for loop or print array function.<\/p>\n
