Array An array is a special variable, which can hold more than one value at a time. Contoh : $cars1="Volvo"; $cars2="BMW"; $cars3="Toyota"; Bisa diganti dengan : $cars=array("Volvo","BMW","Toyota");
3
Tipe Array In PHP, there are three types of arrays:
Indexed arrays - Arrays with numeric index Associative arrays - Arrays with named keys Multidimensional arrays - Arrays containing one or more arrays
4
PHP Indexed Arrays The index can be assigned automatically (index always starts at 0): $cars=array("Volvo","BMW","Toyota"); or the index can be assigned manually: $cars[0]="Volvo"; $cars[1]="BMW"; $cars[2]="Toyota";

Cara memanggil isi array: <
Cara memanggil isi array: <?php $cars=array("Volvo","BMW","Toyota"); echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . "."; ?> Cara menghitung isi array : <?php $cars=array("Volvo","BMW","Toyota"); echo count($cars); ?>

<?php $cars=array("Volvo","BMW","Toyota"); $arrlength=count($cars); for($x=0;$x<$arrlength;$x++) { echo $cars[$x]; echo "<br>"; } ?>
![< php $cars=array( Volvo , BMW , Toyota ); $arrlength=count($cars); for($x=0;$x<$arrlength;$x++) { echo $cars[$x]; echo <br> ; } >](http://slideplayer.com./slide/12249783/72/images/6/%3C+php+%24cars%3Darray%28+Volvo+%2C+BMW+%2C+Toyota+%29%3B+%24arrlength%3Dcount%28%24cars%29%3B+for%28%24x%3D0%3B%24x%3C%24arrlength%3B%24x%2B%2B%29+%7B+echo+%24cars%5B%24x%5D%3B+echo+%3Cbr%3E+%3B+%7D+%3E.jpg "< php $cars=array( Volvo , BMW , Toyota ); $arrlength=count($cars); for($x=0;$x<$arrlength;$x++) { echo $cars[$x]; echo <br> ; } >")

PHP Associative Arrays
Associative arrays are arrays that use named keys that you assign to them. There are two ways to create an associative array: $age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43"); or: $age['Peter']="35"; $age['Ben']="37"; $age['Joe']="43";
8
Cara memanggil : <?php $age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43"); echo "Peter is " . $age['Peter'] . " years old."; ?> Cara loop : <?php $age=array("Peter"=>"35","Ben"=>"37","Joe"=>"43"); foreach($age as $x=>$x_value) { echo "Key=" . $x . ", Value=" . $x_value; echo "<br>"; } ?>

Form Cara mengirim : <html> <body> <form action="welcome.php" method="post"> Name: <input type="text" name="name"><br> <input type="text" name=" "><br> <input type="submit"> </form> </body> </html> Cara memanggil: <html> <body> Welcome <?php echo $_POST["name"]; ?><br> Your address is: <?php echo $_POST[" "]; ?> </body> </html>
10
Form Cara mengirim : <html> <body> <form action="welcome.php" method=“get"> Name: <input type="text" name="name"><br> <input type="text" name=" "><br> <input type="submit"> </form> </body> </html> Cara memanggil: <html> <body> Welcome <?php echo $_GET["name"]; ?><br> Your address is: <?php echo $_GET[" "]; ?> </body> </html>
