PHP Create Arrays
You can create arrays by using the array() function:
Example
<!DOCTYPE html>
<html>
<body>
<pre>
<?php
$cars = array("Volvo", "BMW", "Toyota");
var_dump($cars);
?>
</pre>
</body>
</html>
Output
array(3) {
[0]=>
string(5) "Volvo"
[1]=>
string(3) "BMW"
[2]=>
string(6) "Toyota"
}
• Multiple Lines
Line breaks are not important, so an array declaration can span multiple lines:
Example
<!DOCTYPE html> <html> <body> <pre> <?php $cars = [ "Volvo", "BMW", "Toyota" ]; var_dump($cars); ?> </pre> </body> </html>
Output
array(3) {
[0]=>
string(5) "Volvo"
[1]=>
string(3) "BMW"
[2]=>
string(6) "Toyota"
}
• Trailing Comma
A comma after the last item is allowed:
Example
<!DOCTYPE html> <html> <body> <pre> <?php $cars = [ "Volvo", "BMW", "Toyota", ]; var_dump($cars); ?> </pre> </body> </html>
Output
array(3) {
[0]=>
string(5) "Volvo"
[1]=>
string(3) "BMW"
[2]=>
string(6) "Toyota"
}
• Loop Through an Indexed Array
To loop through and print all the values of an indexed array, you could use a foreach loop, like this:
Example
Display all array items:
<!DOCTYPE html>
<html>
<body>
<?php
$cars = array("Volvo", "BMW", "Toyota");
foreach ($cars as $x) {
echo "$x
";
}
?>
</body>
</html>
Output
Volvo
BMW
Toyota
