PHP Array Exercises : Generate an array with a range taken from a string
PHP Array: Exercise-29 with Solution
Write a PHP program to generate an array with a range taken from a string.
Sample Solution:
PHP Code:
<?php
function string_range($str1)
{
preg_match_all("/([0-9]{1,2})-?([0-9]{0,2}) ?,?;?/", $str1, $a);
$x = array ();
foreach ($a[1] as $k => $v)
{
$x = array_merge ($x, range ($v, (empty($a[2][$k])?$v:$a[2][$k])));
}
return ($x);
}
$test_string = '1-2 18-20 9-11';
print_r(string_range($test_string));
?>
Sample Output:
Array ( [0] => 1 [1] => 2 [2] => 18 [3] => 19 [4] => 20 [5] => 9 [6] => 10 [7] => 11 )

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(); ?>
