NeMSeR's Arrays PHP Tutorial

This will basically explain how to handle and set arrays.

First of all lets assume a previous page has been made which lets users enter 3 fields of text containing their favourite movies. This tut will be demonstrated by using the action="example_page.php" commands in the form.

Now first of all we want to set an array. To do this we use this command:

PHP Code:

$movies = array(); 


Assuming that the 3 textfields on the previous page's form are called movie1, movie2 and movie3 we will use this to input that information into the array.

PHP Code:

$movies = array($_POST['movie1'], $_POST['movie2'], $_POST['movie3']); 


Once we have done that we can call the array by using this.

PHP Code:

echo "The movies are $movies"; 


Now, your probably wondering how we seperate each string inside the array. Well that is done by using foreach. This is an example, this code will print each movie on a different line.

PHP Code:

foreach ($movies as $value) {
echo $value . "<br>";
} 


Here is it all put together, i have also added a little something else to put them in alphabetical order.

PHP Code:

    //first of all we shall set the array 
$movies = array($_POST['movie1'], $_POST['movie2'], $_POST['movie3']); 

//next we will put them in alphabetical order 
asort($movies); 

//now we will split the array and show the results 
foreach ($movies as $value) { 
echo $value . "<br>"; 
} 


That's it for arrays, if you want anything simplified then reply here.
