PHP Array Exercises : Sort an associative array by values

PHP Array: Exercise-34 with Solution

Write a PHP program to sort an associative array (alphanumeric with case-sensitive data) by values.

Sample Solution:

PHP Code:

<?php
$test_array = array(
    0 => 'example1',
    1 => 'Example11',
    2 => 'example10',
    3 => 'Example6',
    4 => 'example4',
    5 => 'EXAMPLE40',
    6 => 'example10'
);
asort($test_array, SORT_STRING | SORT_FLAG_CASE | SORT_NATURAL);
print_r($test_array);
?>

Sample Output:

Array                                                       
(                                                           
    [0] => example1                                         
    [4] => example4                                         
    [3] => Example6                                         
    [2] => example10                                        
    [6] => example10                                        
    [1] => Example11                                        
    [5] => EXAMPLE40                                        
)

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(); ?>
