Have a look at $_SERVER[‘REQUEST_URI’], i.e. $actual_link = “http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]”; (Note that the double quoted string syntax is perfectly correct) If you want to support both HTTP and HTTPS, you can use $actual_link = (isset($_SERVER[‘HTTPS’]) && $_SERVER[‘HTTPS’] === ‘on’ ? “https” : “http”) . “://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]”; Editor’s note: using this code has security implications. The client can … Read more
A query may fail for various reasons in which case both the mysql_* and the mysqli extension will return false from their respective query functions/methods. You need to test for that error condition and handle it accordingly. mysql_ extension: NOTE The mysql_ functions are deprecated and have been removed in php version 7. Check $result … Read more
The time would go by your server time. An easy workaround for this is to manually set the timezone by using date_default_timezone_set before the date() or time() functions are called to. I’m in Melbourne, Australia so I have something like this: date_default_timezone_set(‘Australia/Melbourne’); Or another example is LA – US: date_default_timezone_set(‘America/Los_Angeles’); You can also see what … Read more
On the command line execute: php –ini You will get something like: Configuration File (php.ini) Path: /etc/php5/cli Loaded Configuration File: /etc/php5/cli/php.ini Scan for additional .ini files in: /etc/php5/cli/conf.d Additional .ini files parsed: /etc/php5/cli/conf.d/curl.ini, /etc/php5/cli/conf.d/pdo.ini, /etc/php5/cli/conf.d/pdo_sqlite.ini, /etc/php5/cli/conf.d/sqlite.ini, /etc/php5/cli/conf.d/sqlite3.ini, /etc/php5/cli/conf.d/xdebug.ini, /etc/php5/cli/conf.d/xsl.ini That’s from my local dev-machine. However, the second line is the interesting one. If there is … Read more
By using $_SERVER[‘REQUEST_METHOD’] Example if ($_SERVER[‘REQUEST_METHOD’] === ‘POST’) { // The request is using the POST method } For more details please see the documentation for the $_SERVER variable.
While you’re usually fine without it, you can and should set the Content-Type header: <?php $data = /** whatever you’re serializing **/; header(‘Content-Type: application/json; charset=utf-8′); echo json_encode($data); If I’m not using a particular framework, I usually allow some request params to modify the output behavior. It can be useful, generally for quick troubleshooting, to not … Read more
Using array_search() and unset, try the following: if (($key = array_search($del_val, $messages)) !== false) { unset($messages[$key]); } array_search() returns the key of the element it finds, which can be used to remove that element from the original array using unset(). It will return FALSE on failure, however it can return a false-y value on success … Read more
You use: public scope to make that property/method available from anywhere, other classes and instances of the object. private scope when you want your property/method to be visible in its own class only. protected scope when you want to make your property/method visible in all classes that extend current class including the parent class. If … Read more
stdClass is just a generic ’empty’ class that’s used when casting other types to objects. Despite what the other two answers say, stdClass is not the base class for objects in PHP. This can be demonstrated fairly easily: class Foo{} $foo = new Foo(); echo ($foo instanceof stdClass)?’Y’:’N’; // outputs ‘N’ I don’t believe there’s … Read more
You should implement a session timeout of your own. Both options mentioned by others (session.gc_maxlifetime and session.cookie_lifetime) are not reliable. I’ll explain the reasons for that. First: session.gc_maxlifetime session.gc_maxlifetime specifies the number of seconds after which data will be seen as ‘garbage’ and cleaned up. Garbage collection occurs during session start. But the garbage collector … Read more
