String
Variables in PHP
String variables are used for values
that contain characters.
In this chapter we are going to look
at the most common functions and operators used to manipulate strings in PHP.
After we create a string we can
manipulate it. A string can be used directly in a function or it can be stored
in a variable.
Below, the PHP script assigns the
text "Hello World" to a string variable called $txt:
<?php
$txt="Hello World";
echo $txt;
?>
$txt="Hello World";
echo $txt;
?>
The output of the code above will
be:
Hello World
