Definition: In programing a string is a sequence of letters, numbers or symbols. Although it can contain numbers, a string does not represent a numeric value (other than perhaps 0 or 1 to determine if it exists). Some examples of strings are:
<?php
$string1 = "This is a string";
//a string can be a sentence
$string2 = "String";
//a string can be a word
$string3 = "Blue22";
//a string can contain numbers
$string4 = "The number 4 can be written as #4";
//a string can contain symbols
?>
