In PHP, I am getting numbers from a database with 3 decimal places. I want to remove the last decimal point. So 2.112 will become 2.11, 23.123 will become 23.12 and 123.267 will become 123.26. Its like doing a floor at a decimal level.

You can use
number_format
, you specify the number of decimal places as the second arugment.Example
$number = 534.333; echo number_format($number,2) // outputs 534.33
Or use
round
$number = 549.333; echo round($number, 2) // outputs 534.33
Seems like
substr
is what solved the question in the endsubstr($number,0,-1); // everything besides the last decimal
