Strings
Strings in PHP could be thought of as sentences such as: "I went to the store". Strings differ from variables in that they are a COLLECTION of values in one variable.
Example:
<?php
$variable = '9';
$string = 'abcdefghijklmnopqrstuvwxyz';
?>Stings can be used to store names, tiles, addresses, and all kinds of things. So expect to use them often! Just like variables - you don't need to tell the computer that it is a "string". The computer can tell just by what value you put in it.
<?php
$1 = 0; //var
$2 = 'Hi'; //string
$3 = "Fast Monkey"; //string
$4 = 'K'; //var
?>I highly recommend you read Codewalkers String Primer.
Here are some links to help you learn more about strings:
tizag.com - Strings
Zend.com - Adv. Strings
PHP - Strings Type
The difference between a variable and a string is that a variable for the value will house only 1 character (rather number or letter) and a string, the value is more then 1 character (rather number or letter). Are my examples below correct?
// this is a variable
$variable = '4';
// this is a string
$variable = '456344534';
// another string
$teacher = "Ms. Doughtfire";
// another variable
$school_code = '9';
Is this correct?

except for this one:
<?php
// this is a string
$variable = '456344534';
?><?php
// this is a string
$variable = "456344534";
// this is a variable
$variable = 456344534;
// this is a variable
$variable = '456344534';
// this is a string
$variable = 'hi';
?>Oh okay. I got that now. Im going to add this to my notes.
