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)You can simply add this function in your config file and set it to a maximum number.
$cfg['MaxNavigationItems'] = 100For more details, check out the documentation here.
To access a URL with authentication, you can simply add the username and password so you don’t have to type it in anymore.
But this is NOT advisable for security reasons as your browser then contains a copy of your credentials.
Syntax:
https://username:password@theurl.com/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);
If you are dealing with money on your code, you must know how to display comma when it reaches a thousand or million or billion and so on. You also need to handle the decimal places. Money usually have only 2 decimal places. If the money is a whole number, you still need to add 2 zeroes as decimals.
Good news! PHP has a built-in function that can do this for you. All you have to do is to call number_format
Example 1:
$number = 123456789.12345;
echo number_format($number, 2);Output 1:
123,456,789.12Example 2:
$number = 9876;
echo number_format($number, 2);Output 2:
9,876.00As I was developing an audio player and creating its embed code, I learned that you can use 2 forward slashes as a shorthand whether a file could be loaded from either an http or https protocol. This shorthand is commonly known as protocol relative URLs.
The browser appends the right protocol in front of the URL.
For example,
//example.com/mycss.cssAs I was telling earlier, it would prepend the right protocol into this https://example.com/mycss.css
So next time, if you want to load up a URL but not quite sure as to what protocol to use, you can just simply use the shorthand — 2 forward slashes.
