PHP Tutorial

[Zenax]

Well I thought in order to test my skills I would write a tutorial on PHP! It is only basic, so to help out others etc.

<?php
echo ('Hello World');
?>

Result: Hello World is written to the page!

<?php
$text = "Hello World!";

echo ($text);
?>

Result is still Hello World on the page, however the text is stored in the variable $text

<?php

$text[1] = "Hello World!";
$text[2] = "Hello Monkey!";

echo ($text[1]);
echo ($text[2]);


?>

Result is Hello World! Hello Monkey, written to the page. The variable is the same however the instances of them are different. Note the [1] and [2] next to them.

Hope you find it simple and easy to understand.

You have this:

 <?php

$text[1] = "Hello World!";
$text[2] = "Hello Monkey!";

echo ($text[1]);
echo ($text[2]);


?>

This should also work, not tested.

<?php

// $text is an array!
$text[1] = "Hello World!";
$text[2] = "Hello Monkey!";

foreach ($text as $echo) {

echo $echo;

}

?>

Functions used: foreach(), echo()

Or, for the array, you could do this:

<?php
  $text= array("Hello World!","Hello Monkey!");
  // Note that the first item in the array would be $text[0]
?>

Or this:

<?php
  $text= array(1 => "Hello World!", 2 => "Hello Monkey!");
?>

Or this:

<?php
  $text= array("world" => "Hello World!", "monkey" => "Hello Monkey!");
?>

All three achieve the same result. All are tested and all work.

Or if you want to be advanced you can do this.

<?php

$words = "Hello World!,Hello Monkey!";

$text = explode(",",$words);

?>

Of course, untested

Functions used: explode()

Thank you guys! This was meant to be simple and easy for beginners and now I have fount even more ways of achieving this!

im just picking things up as I go along, like i got the $text[1] thing from a login script t2t2 wrote for me!

Indeed you did I bet.

You can also do: $text['brandonrules']

that works too, just edit the 'brandonrules' to other text.

<?
$text = 'Hello';
if ($text = 'Hello') print $text .' World!'; // Hello World!
if ($text) print "$text World!"; // Hello World!
print '$text World'; // $text World
// (in single-quote, variables don't get changed, with double-quotes, PHP will ALWAYS look for a variable,
// so its most efficient to use first print)
print 'I said Hello to you at '. date(r) .'!';
?>

Thanks again guys!

I wrote this:

<?php

class hello
{

	function world()
	{
	
		echo ('Hello World!');
		
	}
	
	function monkey()
	{
	
		echo('Hello Monkey!');
		
	}
	
}

$helloworld = new hello;
echo $helloworld -> world();

print '<br />';

echo $helloworld -> monkey();

?>

It works, and does exactly the same as what the others do XD

There was no need for the second: $helloworld = new hello;
