I love Linux!! - Mosh awy -

Wordpress 2.6, again, they always impresses me!

PHP, MySQL, Java and SCJP!

Smileys, again

One of the most amazing features in php is how it shows errors to the developer, you might think of it as a GPS which tells you exactly where you have to go ; Line Number, character and the error itself..CHARM!

Through the whole previous 2 years, I didn’t use error reporting at all, because it was off by default on my localhost - I use Fedora with Apache, php and MySQL installed as my localhost,, I even installed phpMyAdmin . -. I didn’t even mind to set it on, may be because I didn’t right that HUGE script that I may search for an error in and get lost. I have to tell that this really enhances your skills a bit, because you become more into code trying to figure out the semi-colon that you forgot and it terminated the script with a blank screen. Anyway, today I thought about giving it a try so I had to do it manually so you should do the following:

$ su -

- then enter the root's password and press enter -

# vi /etc/php.ini

Search for “Error handling” (type /Error handling and press enter in vi), this is where the error handling and logging configuration block starts. Try to find the statement where it says:

;error_reporting = E_ALL

If it had a semi-colon (;) in the beginning, just remove it, if there where no semi-colons - the common situation - , go to the next step.

Next, search for “display_error” (type /display_errors and press enter in vi), mostly you will find this equals Off so you will find it saying:

display_errors = Off

Change the “Off” to “On”, save the configuration file ( Shift+ZZ in vi) and issue the following command to restart the web server service:

# service httpd restart

If you had any problems, please report them here.

It’s known that declaring a php function has the following syntax:

<?php
function function_name(Parameters_list) {
// function
// code
// block
}
?>

an example of this can be like this:

<?php
function nameAndAge($name,$age){
echo "Welcome $name, you are $age years old!";
}
?>

When I issue the following statement:

<?php
nameAndAge("bingorabbit",20);
?>

I will get:
Welcome bingorabbit, you are 20 years old!

Most of us know that, and also we know that to set a default value for any parameter, we can do the following:

<?php
function function_name($parameter1 = "default value", rest_of_the_parameter_list) {
// function
// code
// block
}
?>

which might take the following form:

<?php
function nameAndAge($name="bingorabbit",$age){
echo "Welcome $name, you are $age years old!";
}
?>

so when I issue:

<?php
nameAndAge();
?>

I will get:
Welcome bingorabbit, you are years old!

and when I issue:

<?php
nameAndAge("Ahmed", 15);
?>

I will get:
Welcome Ahmed, you are 15 years old!

The problems is such declaration is that, you can’t just issue:
