Extension

Zend\Validator\File\Extension checks the extension of files. It will assert true when a given file has one the a defined extensions.

This validator is inversely related to the ExcludeExtension validator.

Supported Options

The following set of options are supported:

• extension (string|array)

  Comma-delimited string (or array) of extensions to test against.

• case (boolean) default: "false"

  Should comparison of extensions be case-sensitive?

Usage Examples

// Allow files with 'php' or 'exe' extensions
$validator = new \Zend\Validator\File\Extension('php,exe');

// ...or with array notation
$validator = new \Zend\Validator\File\Extension(array('php', 'exe'));

// Test with case-sensitivity on
$validator = new \Zend\Validator\File\Extension(array('php', 'exe'), true);

// Perform validation
if ($validator->isValid('./myfile.php')) {
    // file is valid
}
