Title says it all.
Though the manual says you're better off to avoid a function call, I've also read $array[] is much slower than array_push(). Does anyone have any clarifications or benchmarks?
Thank you!

To add one element to the array it's better to use $array[] = because in that way.

Is it better in C++ to pass by value or pass by constant reference?
I am wondering which is better practice. I realize that pass by constant reference should provide for better performance in the program because you are not making a copy of the variable...

Here is an example, assume you have.
For some basic types the performance in general the same both for passing, such as a pair of ints can perform better by passing by value.

If you are doing something like the following:
var i = $('input[@name=some_field]'); if (i.val() != '' && !(i.val() >=1 && i.val() <= 36) || i.val() == 'OT')) { i.focus(); }
is i.val() fast enough to use it multiple times or should you do:
var value...

If we want to get a value from a method, we can use either return value, like this:
public int GetValue();
or:
public void GetValue(out int x);
I don't really understand the differences between them, and so, don't know which is better. Can you explain...

Whether it's better or not is subjective.

You should be able probably make the string value visible to the 3rd party code
public class MyClass", LastName = "Jordon" }, new Person() { FirstName = "Larry", LastName....
Have a return value, so the 3rd party code must be reading properties.

Obtain the XML as a string using the GetValue method or Value property.

Here's my code:
$quizId = ''; foreach ($module['QuizListing'] as $quizListing) { if ($quizListing['id']) { $quizId = $quizListing['id']; break; } }
Is there a better way of doing this?

If you want to associate some constant value with a class, here are two ways to accomplish the same goal:
