The following code does not work properly

$number = "999.00";
$precision = 2;
echo preg_replace("/\.0{$precision}/", "", $number);

it echos 999.00

But if you escape the first `{' bracket, the regular expression works properly

echo preg_replace("/\.0\{$precision}/", "", $number);

it echos 999

The {$var} construct is interpreted specially in the double-quoted strings by the Zend engine - it will interpolate the variable so you indeed need to escape it with a backslash. This is not a PCRE problem.
