Convert a PHP object to an associative array
...either side.
Example: Simple Object
$object = new StdClass;

Output:
array(2) {
'foo' => int(1)
'bar' => int(2)
}
Example: Complex Object
class Foo
{
private $foo;
protected $bar;
public $baz;

Where do “pure virtual function call” crashes come from?
... using namespace std;
char pool[256];
struct Base
{
virtual void foo() = 0;
virtual ~Base(){};
};
struct Derived: public Base
{
virtual void foo() override { cout <<"Derived::foo()" << endl;}
};
int main()
{
auto* pd = new (pool) Derived();

Calling parent class __init__ with multiple inheritance, what's the right way?
...each other, they're not designed for multiple inheritance. Example:
class Foo:
def __init__(self):
self.foo = 'foo'
class Bar:
def __init__(self, bar):
self.bar = bar

CSS Selector that applies to elements with two classes
...
Chain both class selectors (without a space in between):
.foo.bar {
/* Styles for element(s) with foo AND bar classes */
}
If you still have to deal with ancient browsers like IE6, be aware that it doesn't read chained class selectors correctly: it'll only read the last clas...
Apk location in New Android Studio
..., and the recommended one in general is Gradle.
For a new project called "Foo", the structure under the main folder will be
Foo/
settings.gradle
Foo/
build.gradle
build/
Where the internal "Foo" folder is the main module (this structure allows you to create more modules l...
Static variables in member functions
...
Since class A is a non-template class and A::foo() is a non-template function. There will be only one copy of static int i inside the program.
Any instance of A object will affect the same i and lifetime of i will remain through out the program. To add an example:
A o...
Initializing C# auto-properties [duplicate]
...w was written before C# 6 came along. In C# 6 you can write:
public class Foo
{
public string Bar { get; set; } = "bar";
}
You can also write read-only automatically-implemented properties, which are only writable in the constructor (but can also be given a default initial value:
public clas...
How to extract a git subdirectory and make a submodule out of it?
...roject
# Create a branch which only contains commits for the children of 'foo'
git subtree split --prefix=foo --branch=foo-only
# Remove 'foo' from the project
git rm -rf ./foo

Passing argument to alias in bash [duplicate]
...eding to be or able to be passed as explicit arguments (e.g. $1).
$ alias foo='/path/to/bar'
$ foo some args
will get expanded to
$ /path/to/bar some args
If you want to use explicit arguments, you'll need to use a function
$ foo () { /path/to/bar "$@" fixed args; }
$ foo abc 123
will be ex...
