Strings

A string is series of characters. In PHP, a character is the same as a byte, that is, there are exactly 256 different characters possible. This also implies that PHP has no native support of Unicode. www.soulfulsax.com See utf8_encode() and utf8_decode() for some Unicode support.

Note:

It is no problem for a string to become very large. There is no practical bound to the size of strings imposed by PHP, so there is no reason at all to worry about long strings.

Syntax

A string literal can be specified in three different ways.

single quoted
double quoted
heredoc syntax
Single quoted
The easiest way to specify a simple string is to enclose it in single quotes (the character ').

To specify a literal single quote, you will need to escape it with a backslash (\), like in many other languages. If a backslash needs to occur before a single quote or at the end of the string, you need to double it. www.saintvsbuddha.com Note that if you try to escape any other character, the backslash will also be printed! So usually there is no need to escape the backslash itself.
