Use Array.prototype.sort(), eg The sort() method accepts a comparator function. This function accepts two arguments (both presumably of the same type) and it’s job is to determine which of the two comes first. It does this by returning an integer Negative (less-than zero): The first argument comes first Positive (greater-than zero): The second argument comes first Zero: The arguments are considered … Read more
Check the manual for mysql_fetch_object(). It returns an object, not an array of objects. I’m guessing you want something like this Might I suggest you have a look at PDO. PDOStatement::fetchAll(PDO::FETCH_OBJ) does what you assumed mysql_fetch_object() to do
If you know the settings in advance you can define it in a single statement: If you don’t know the values in advance you can just define the top level object and then add properties: Or half-way between the two, define the top level with nested empty objects as properties and then add properties to … Read more
Isn’t this the normal way to free the memory associated with an object? This is a common way of managing dynamically allocated memory, but it’s not a good way to do so. This sort of code is brittle because it is not exception-safe: if an exception is thrown between when you create the object and … Read more
Use usort, here’s an example adapted from the manual: You can also use any callable as the second argument. Here are some examples: Using anonymous functions (from PHP 5.3) usort($your_data, function($a, $b) {return strcmp($a->name, $b->name);}); From inside a class usort($your_data, array($this, “cmp”)); // “cmp” should be a method in the class Using arrow functions (from PHP 7.4) usort($your_data, fn($a, $b) => strcmp($a->name, … Read more
No, there’s not any alternative to using <object> 2) It’s Adobe Flash (read about it in Wiki) 3) It’s being deprecated. Various browsers stopped or will stop support of Adobe Flash in a year or two. 4) That’s why you should prepare to switch your client ads/convert them to HTML5 (it’s a next rich media format, … Read more
The __str__ method is what gets called happens when you print it, and the __repr__ method is what happens when you use the repr() function (or when you look at it with the interactive prompt). If no __str__ method is given, Python will print the result of __repr__ instead. If you define __str__ but not __repr__, Python will use what you see above as the __repr__, but still use __str__ for … Read more
Native deep cloning It’s called “structured cloning”, works experimentally in Node 11 and later, and hopefully will land in browsers. See this answer for more details. Fast cloning with data loss – JSON.parse/stringify If you do not use Dates, functions, undefined, Infinity, RegExps, Maps, Sets, Blobs, FileLists, ImageDatas, sparse Arrays, Typed Arrays or other complex types within your object, a … Read more

will have the same effect using “native” code. Edit Since this gets a lot of views, note (per @oriol’s comment) that the following more concise expression is effectively equivalent: But note per @JussiR’s comment, that unlike the “verbose” form, it does create an empty, unused, and indeed unusable array instance in the process. What compilers do about … Read more
