I am trying to change variable names using a for loop. How do you do this? Here is what I have been trying. Obvious it iswrong because I get an error

for ($i = 0; $i < 5; $i++) {
if ($CourseName$i != "") {
CODE HERE
}
}

Thanks

You want to use 'Variable Variables' mate.

For example:

<?
$CourseName1 = "TEST";
$CourseName3 = "TEST2";

for ($i = 0; $i < 5; $i++) 
{ 
	$varname = "CourseName".$i;

if ($$varname != "") 
{ 
	echo $$varname."<br>"; 
} 
else
{
	echo $varname." is empty<br>";
}
} 
?>
