I recently discovered the joys of using heredoc with sprintf and positions. Useful if you want some
code to iterate, you can repeat placeholders.
<?php
function getNumber($num = 0) {
$foo = rand(1,20);
return ($foo + $num);
}
function getString() {
$foo = array("California","Oregon","Washington");
shuffle($foo);
return $foo[0];
}
function getDiv() {
$num = getNumber();
$div = sprintf( "<div>%s</div>", getNumber(rand(-5,5)) );
return $div;
}
$string = <<<THESTRING
I like the state of %1\$s <br />
I picked: %2\$d as a number, <br />
I also picked %2\$d as a number again <br />
%3\$s<br />
%3\$s<br />
%3\$s<br />
%3\$s<br />
%3\$s<br />
THESTRING;
$returnText = sprintf( $string, getString(),getNumber(),getDiv() );
echo $returnText;
?>
Expected output of the above code:
I like the state of Oregon
I picked: 15 as a number,
I also picked 15 as a number again
5
5
5
5
5
