PHP dropping decimals without rounding up

Question

I want to drop off decimals without rounding up. For example if I have 1.505, I want to drop last decimal and value should be 1.50. Is there such a function in PHP?

Answer 1

$num = 118.74999669307;
$cut = substr($num, 0, ((strpos($num, '.')+1)+2));`
// Cut the string from first character to a length of 2 past the decimal.
/ substr(cut what, start, ( (find position of decimal)+decimal itself)+spaces after decimal) )
echo $cut; 

this will help you shorten the float value without rounding it..
