[SOLVED] If decimal exists then stop looping

[KingOfHeart]

I want to divide a number in php. Then if that number has a decimal I want to stop a while loop. Oviously strpos does not work.

 

while($n < strlen($fileData)) {

	$n++;
	if($num == 0)
	{
		$x = $fileData[$n] / 32;
		if(strpos($x,".") === false)
		{
			echo "X:" . $x . " ";
		}
		else
		{
			echo "stopped";
			return;
		}

	}
	else if($num == 1)
	{
		$y = $fileData[$n] / 32;
		if(strpos($y,".") === false)
		{
			echo "Y:" . $y . " ";
		}
		else
		{
			echo "stopped";
			return;
		}
	}
	echo $fileData[$n] . "<br>";
	$num++;
}

How about...

 

if(!is_int($value)) {
   break;
}

or

 

if (($fileData[$n] % 32) != 0) { 
  // is decimal
}
