Looking for a code to extract the rest of the URL except the domain name. Here it is:
$path = 'http://winnieverzosa.com/whatever/path/?query=something';
preg_match('/^[^#]*?:\/\/.*?\/(.*)$/', $path, $matches);
echo $mathces[1];
Output:
whatever/path/?query=something
By using the getMethods() function from ReflectionClass you are able to get all the methods in a class.
Simply create an object of the ReflectionClass with one argument, the class name you want to access. Then, use the getMethods() function and assign the result to a variable.
$class_obj = new ReflectionClass('myClass');
$array_of_methods = $class_obj -> getMethods();
var_dump($array_of_methods);You can simply use the built-in function method_exists() and it will return a boolean true if it exists and false if it doesn’t.
Example Usage:
$class_obj = new ClassName();
var_dump( method_exists($class_obj, 'myMethodName') );
Example Output:
bool(true)Oftentimes, file_get_contents() function comes really handy when we are trying to pull data from an API. We can simply do it by doing this:
$json_data = file_get_contents('http://theurl.com/api/json');
But what if the API requires authentication? Then, you’ll need a way to communicate with the authenticated server or else the server will give you this response.
Warning: file_get_contents(http://www.yourdomain.com/file.php): failed to open stream: HTTP request failed!
HTTP/1.1 401 Authorization Required in file.php on line 7In order to avoid that, first we need a way to add the username and password to the HTTP header in the request. We can simply use the stream_context_create() function.
Next is to use that stream context in the file_get_contents() function as the third parameter. As for the second parameter, just simply use false or 0 to skip it.
$username = 'theusername';
$password = 'thepassword';
$context = stream_context_create(array(
'http' => array(
'header' => "Authorization: Basic " . base64_encode("$username:$password")
)
));
$json_data = file_get_contents('https://theurl.com/api/json', false, $context);
