Getting Started - Become PHP Expert in 30 days.

What is PHP

PHP is a programming language, created for web development.

Who Use PHP

Facebook, Yahoo, Wikipedia, Flickr, SourceForge, Photobucket and many other large sites use PHP.

Lets Say Hello to PHP

This is your first PHP program.

Create a file

hello.php

Paste following content to that file.

PHP Code:

<?php echo "Hello from PHP";

This is very basic PHP program. Upload it to web site (or local web server), access it with url

http://yoursite/hello.php

In this program, we use one PHP command (programmers call these commands functions) echo. echo function is used to display text. Try changing the text and see how it works.

Find

PHP Code:

echo "Hello from PHP";

Replace with

PHP Code:

echo "I am a PHP Programmer now";

or

PHP Code:

echo "I have 10 cats and 2 dogs";

Exercise

In PHP each instructions end with semicolon (;).

Remove ; from end of PHP line, upload the file to web server and see what error you get.

Successfully uploaded my first php file. You can view the same at

http://php.flashwebhost.com/vineesh/hello.php

But I didn't get any error after removing the ; from end of the line. My code is:

Code:

<?php echo "I am becoming a PHP programmer" ?>

One more thing I noticed,

In the code you given in Day 1 Post (here), under the line 'Paste following content to that file.'

Code:

<?php echo "Hello from PHP";

Seems '?>' missing.

Is that not compulsory or you missed it?

As per PHP coding standward, we don't need ending ?>

From

http://www.php-fig.org/psr/psr-2/

Quote:

The closing ?> tag MUST be omitted from files containing only PHP.

Look like this is because latest PHP can handle single line PHP code with out ending semicolon. But we will need semicolon as almost every php code have more than one line.

As per PHP Coding Style Guide never use ending ?>

http://www.php-fig.org/psr/psr-2/

Only use ?> if you want to write non PHP code after PHP Code block ended, for example

Code:

<html> <body> <?php echo "Welcome"; ?> </body> </html>

Good, we can use signle quote instead of double quote, that is the recommended and faster way. For example

Code:

<?php echo '<B><h1>I have 10 cats and 2 dogs</h1></B>' ;

Don't use closing tag for PHP only code.

Code:

<?php echo "I am an Indian!";

This is fine.

Good wok, experiment with the code like that, make mistakes, fix it, you won;t forget.

Can anyone tell how to fix the error in following code

hello_2.php

Code:

<?php echo 'Ranan's new production - Andhar Nogori Choupot Raja';

That is one way. It is better use single quote for string when ever possible.

Code:

<?php echo 'Ranan\'s new production - Andhar Nogori Choupot Raja';

My Code:

Code:

<?php echo 'I am <b>Vineesh Mohan</b>. <br /> <br /> Working in <b><I> <a href="http://www.FlashWebHost.com">FlashWebHost.com</a></I></b> <br /> <br /> My collegues are <br /><br /> <b>Tom <br /> Sherly <br /> Annie <br /> Sibichan <br /> Suneesh <br /> Steephan <br /> Ramesh <br /> and Mini</b>';

Is there any other way to insert line breaks in php ?
05-08-2014, 11:35 AM

PHP don't have line breaks. You have to use HTML <br>

HTML 5, you don't need to close Tags like img, br. So just use <br> instead of <br />

Ok, now my code is:

Code:

<?php echo 'I am <b>Vineesh Mohan</b>. <br> <br> Working in <b><I><a href="http://www.FlashWebHost.com">FlashWebHost.com</a></I></b> <br> <br> My collegues are <br><br> <b>Tom <br> Sherly <br> Annie <br> Sibichan <br> Suneesh <br> Steephan <br> Ramesh <br> and Mini</b>';

Code:

<?php echo '<h1><b><center>Prayer</center></b></h1>' ; echo '<p>A prayer of thanks is something that every person should say everyday. Everyone has something that they are thankful for. Even if it is just getting out of bed every day. A simple prayer of thanks is: God of Love, I thank You for the people in my life who are easy to love. I thank You for my family and friends who understand my actions, who support me in my decisions, and whose presence can lift the burden of a thorny day. Help me with those who are difficult to love. Let me recognize their flaws and their dangers. But then let me remember your attitude toward them, and lead me to see them in the light of Your love. Amen. </p>';

Here is an example of escaping string in PHP

Code:

echo '<font color=green><I><U><h1>I have 2 car\'s!</h1></U></I></font>';

echo 'String here';

If string itself contain a single quote, that need to be escaped with \ character like this

Code:

car\'s!
