in this example we have this url
www.htmlexample.org/phpexample.php
Before passing a variable using the url first add a '?' to the end of the normal url
www.htmlexample.org/phpexample.php?
after the ? add the name of the variable
www.htmlexample.org/phpexample.php?varName
put an "=" then add the value assigned to the variable name
www.htmlexample.org/phpexample.php?varName=value
to pass more then one variable repeat above but only have '?' before the first one and a '&' in between each new variable
www.htmlexample.org/phpexample.php?varName=value&othervarName=othervalue
To get the variable values from the url use the $_GET method
for example to get the value of the variable varName use
$_GET["varName"]
use $_GET the same as any other method
this is an example of passing a string variable tom and int variable 22 to the php script
then using the 2 variables in the webpage
www.htmlexample.org/phpexample.php?name=tom&age=22
echo "<h6>Name " . $_GET["name"] . "</h6>";
echo"<h6>Age " . $_GET["age"] . "</h6>";
