PHP Variables
Posted on April 5th, 2009 No commentsIn PHP, variables are used for storing a value, whether it’s a text string or numbers.
A variable in PHP has to start with the ‘$’ sign followed by whatever you want to call the variable and then the variables value which would look something like this:
$dvd = “Casino Royale”
a number can also be stored in a variable:
$ageoffilm = 3
So what would happen if we made a PHP script using these variables?
<?php
$dvd = “Casino Royale”;
$ageoffilm = 3;
?>
<html>
<head><title>Movies</title></head>
<body>
<?php
echo “Best bond film: ” . $dvd . “<br />”;
echo “How old is the film: ” . $ageoffilm . “<br />”;
?>
</body>
</html>
This would output:
Best bond film: Casino Royale
How old is the film: 3By the way you may notice the cotcatination operator which is basically just a period “.”
You can use this operator to add strings together as shown in the example above.
