How do I truncate a decimal in PHP?

Yes intval

intval(1234.567);
intval(-1234.567);

Truncate floats with specific precision:

echo bcdiv(2.56789, 1, 1);  // 2.5
echo bcdiv(2.56789, 1, 3);  // 2.567
echo bcdiv(-2.56789, 1, 1); // -2.5
echo bcdiv(-2.56789, 1, 3); // -2.567

This method solve the problem with round() function.
