PHP Array Exercises : Floor decimal numbers with precision
PHP Array: Exercise-18 with Solution
Write a PHP function to floor decimal numbers with precision.
Note: Accept three parameters number, precision, and $separator
Sample Data :
1.155, 2, "."
100.25781, 4, "."
-2.9636, 3, "."
Sample Solution:
PHP Code:
<?php
function floorDec($number, $precision, $separator)
{
$number_part=explode($separator, $number);
$number_part[1]=substr_replace($number_part[1],$separator,$precision,0);
if($number_part[0]>=0)
{$number_part[1]=floor($number_part[1]);}
else
{$number_part[1]=ceil($number_part[1]);}
$ceil_number= array($number_part[0],$number_part[1]);
return implode($separator,$ceil_number);
}
print_r(floorDec(1.155, 2, ".")."\n");
print_r(floorDec(100.25781, 4, ".")."\n");
print_r(floorDec(-2.9636, 3, ".")."\n");
?>

PHP: Tips of the Day
PHP: Where does PHP store the error log? (php5, apache, fastcgi, cpanel)
PHP stores error logs in /var/log/apache2 if PHP is an apache2 module. Shared hosts are often storing log files in your root directory /log subfolder. But...if you have access to a php.ini file you can do this:
error_log = /var/log/php-scripts.log
According to rinogo's comment: If you're using cPanel, the master log file you're probably looking for is stored (by default) at
/usr/local/apache/logs/error_log
If all else fails you can check the location of the log file using
<?php phpinfo(); ?>
