PHP Tutorial: The Basics

Chapter 2: First steps

First of all you should know that it's possible to use PHP-Code between HTML-Code.

Create a sample.php file in your directory.

<?php

echo "Hello World!";

To use it within your HTML-Code simple use

<h1>This is the Headline</h1>

<?php
echo "Hello World!";
?>

###Schleifen:

Foreach:

$apostles = ['Simon', 'Andrew', 'James'];

foreach($apostles as $apostle)
{
    echo $apostle . '<br />';
}

For:

$apostles = ['John', 'Philip', 'Bartholomew', 'Thomas'];

for($i=0;$i<count($apostles);$i++)
{
  echo $apostles[$i] . '<br />';
}

While:

$apostles = ['Matthew', 'Thaddaeus', 'Judas Iscariot'];

$i = 0;
while($i < count($apostles))
{
    echo $apostles[$i] . '<br />';
    $i++;
}

Do-While:

$apostles = ['James', 'John', 'Philip', 'Bartholomew'];

$i = 0;
do
{
    echo $apostles[$i] . '<br />';
    $i++;
} while($i < count($apostles));
