PHP Get Variables

PHP $_GET Variables

Get variables are variables which are passed into a url. The url will have a name and a value. With this simple example, the link is get.php?variable=5. The key is variable and the value is 5. In simplicity, $_GET[‘variable’] = 5.

<?php 

foreach($_GET as $key => $value){
echo $key."-".$value."<br/>";
}
if($_GET['variable'] == '5'){
echo "Here is the value of the get variable: ".$_GET['variable']."<br/>";
}
?>
<br/>
<a href="get.php?variable=5">Get Variable</a>

This example shows more two get variables in a url. The second variable is separated with the ‘&’ sign. If a third variable is added, it would be separated with a ‘&’ sign too.

<?php 

foreach($_GET as $key => $value){
echo $key."-".$value."<br/>";
}
if($_GET['variable'] == '5'){
echo "Here is the value of the get variable: ".$_GET['variable']."<br/>";
}

if($_GET['secondvariable'] == true){
echo "Here is the value of the second get variable: ".$_GET['secondvariable']."<br/>";
}
?>
<br/>
<a href="get2.php?variable=5&secondvariable=6">Get Two Variables</a>
