Passing an array to a function
Question
I have this PHP code in sample.php:
<html>
<head>
<title>
PHP Test
</title>
<?php
include "sample1.php";
?>
</head>
<body>
<?php
echo "<br> ";
echo arrayAdder([1,2,3,4]);
echo "<br> ";
?>
</body>
</html>
And this is my function located in sample1.php
function arrayAdder($array){
$total = count($array);
return $total;
}
I tried to run sample.php in my browser, but an error occurs saying:
Parse error: syntax error, unexpected '[', expecting ')' in C:\xampp\htdocs\sample.php on line 13
Whats wrong with my code?

the array shorthand syntax is supported by PHP >= 5.4 ( New features ). your version might not support the syntax. check the version. and for now try this -
<?php
echo "<br> ";
echo arrayAdder(array(1,2,3,4));
echo "<br> ";
?>

Short array syntax was added to PHP in version 5.4. You'll need to make sure you're running a version of PHP >= 5.4.
You can check by creating a script with <?php phpinfo(); ?> <?php phpinfo(); ?> as its contents, or running php -v from the command line.
If you're not able to update your PHP to 5.4 or later, you can always switch back to the traditional style of defining arrays, array(1, 2 ,3 ,4) .
