note 74191 added to function.substr

I made a function that removes the last zero's in a string
or integer.

<?php
function removeDotZero($var)
{
	$var = trim($var);

	$pos = strpos($var,".");
	if($pos != false)
	{
		$size = strlen($var);

		for($i = $size; $i > $pos; $i--)
		{
			if(substr($var,-1,1) == "0")
				$var = substr($var,0,($i - 1));
			else if(substr($var,-1,1) == ".")
			{
				$var = substr($var,0,($i - 1));
				break;
			}
			else
				break;
		}

		return $var;
	}
	else
		return $var;
}

echo removeDotZero("100.0052520")."n";
echo removeDotZero("100.0000000")."n";
?>

// produces:
// 100.005252
// 100
