1.2.605. Is An Extension Function¶
This is an extension function.
Almost every PHP extension defines extra functions. Nowadays, they are prefixed, like mysqli_connect, ldap_close, or zlib_decode. Sometimes, they are even in a namespace. Refer to the extension itself to learn more about its functions usage.
<?php
// range is a native PHP function. It is always available
$array = range(0, 100);
// json_encode is an extension function : it requires that PHP was compile with ext/json
echo json_encode($array);
?>
