loop with two variables put together

[cjhowe]

I need to loop this as an echo for a textfield name and i can't quite get the syntax correct.

I have the similar scenario....
<?php

$A1 = 'Dog';
$A2 = 'Cat';
$A3 = 'Horse';

for($i=0;$i<+15;$i++; ) {
echo ($'A'.$i);
}

?>
Where am I going wrong?

You need to use braces, and correct the for loop:

<?php

$A1 = 'Dog';
$A2 = 'Cat';
$A3 = 'Horse';

for ($i = 0; $i <= 15; $i++) {
	echo ${'A' . $i};
}

?>

or perhaps

<?php

$A1 = 'Dog';
$A2 = 'Cat';
$A3 = 'Horse';

for ($i = 0; $i <= 15; $i++) {
	if (isset(${'A' . $i}))
		echo ${'A' . $i};
}

?>

That said, why not use an array?
