But my question was what would be the value when class A is run for the second time (assuming that the threads have incremented the value in the first run of A)?
Look into thread pools in Java Tiger 5.0, Doug Lea's thread packages or the Apache Commons Thread Pool. you could use that technique to increment it every time a thread starts, but be sure to decrement it when the thread ends. Stefan, I am incrementing the count in the run method.
PHP static variable is used to remember the value of a local variable when we call the function in our program.
While your script is running a static variable is only retained by the function , but it is NOT shared with the main code.
Returns the last return value of the function, * * Notes : uses call_user_func_array() so passing parameters doesn't depend on $fun signature * It also returns FALSE upon error.
This means get the current value of x, add one, and then update x with the new value. Although this assignment statement may look a bit strange, remember that executing assignment is a two-step process. Second, let the variable name on the left-hand side refer to this new resulting object.
Assignment to zero, on using static keyword is only for primitive datatypes, not for user defined datatypes.
Among other things, this can be used to implement callbacks, function tables, and so forth.
Variable functions won't work with language constructs such as A good method to pass around variables containing function names within some class is to use the same method as the developers use in preg_replace_callback - with arrays containing an instance of the class and the function name itself.function call_within_an_object($fun)function some_other_fun()class x$x = new x();/* the following line calls $x- If you want to call a static function (PHP5) in a variable method: Make an array of two entries where the 0th entry is the name of the class to be invoked ('self' and 'parent' work as well) and the 1st entry is the name of the function.
In this line, we make an array of months and increases the current value of the $text variable by 1.
This means that if a variable name has parentheses appended to it, PHP will look for a function with the same name as whatever the variable evaluates to, and will attempt to execute it.
Sometimes programmers also talk about bumping a variable, which means the same as incrementing it by 1.
