[RESOLVED] Echo if value

[Jon12345]

I want to echo only if there is a value in $usernamesUnique, so I don't get blank lines. How do I do that?

for ($x = 0; $x < count($usernamesUnique); $x++){ 
        echo "<br>".$usernamesUnique[$x]; 
    } 

Thanks,

Jon

You can use an if statement as empty strings return as false. See example below.

	$usernamesUnique = array('bob','','fred','sally','');

for ($x = 0; $x < count($usernamesUnique); $x++){
	if($usernamesUnique[$x]){
  	echo "<br>".$usernamesUnique[$x];
  }
  }
