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(); ?>
