PHP Array Exercises : Convert a string to an array
PHP Array: Exercise-55 with Solution
Write a PHP function to convert a string to an array (trimming every line and remove empty lines).
Sample Solution:
PHP Code:
<?php
$string = " IANA is the global coordinator of the DNS root.
The root is the upper-most part of the DNS hierarchy,
and involves delegating administrative responsibility
of “top-level domains”, which are the last segment of
a domain name, such as .com, .uk and .nz. Part of this
task includes evaluating requests to change the operators
of country code domains, as well as day-to-day maintenance
of the details of the existing operators. ";
$result = array_filter(array_map('trim', explode("\n", $string)), 'strlen');
print_r($result);
?>
Sample Output:
Array ( [0] => IANA is the global coordinator of the DNS root. [1] => The root is the upper-most part of the DNS hierar chy, [2] => and involves delegating administrative responsibi lity [3] => of “top-level domains”, which are the last segmen t of [5] => a domain name, such as .com, .uk and .nz. Part of this [6] => task includes evaluating requests to change the o perators [8] => of country code domains, as well as day-to-day ma intenance [9] => of the details of the existing operators. )

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(); ?>
