PHP variable and type extension function processing and variable processing Function processing functions: Call_user_func_array-Call a callback with an array of parameters Call_user_func-Call the callback given by the first parameter Create_function-

The significance of *,& in pointer operation(1) *We all know that when you write int *p, you can declare a pointer. Few people know that there is a name of "dereference" in C + +. What he means is to explain the reference, and to say the popular

1. If no method is used, the initial wording should be:functionUnique (arr) {varres=[]; for(vari=0,len=arr.length;i){ varobj =Arr[i]; for(varJ=0,jlen = res.length;j){ if(res[j]===obj) Break; } if(jlen===j) Res.push (obj); }

Six de-duplicated JavaScript Array methods, javascript Array Method 1 Without thinking, we can get the O (n ^ 2) Complexity solution. Define a variable array res to save the result and traverse the array to be de-duplicated. If this element already

1. If no method is used, the initial wording should be:function Unique (arr) { var res=[]; for (Var i=0,len=arr.length;i2. If compatibility is not considered, the indexof () method of the array inside the ES5 is used.function Unique (arr) {

PHP is a weakly typed, dynamic language script. When declaring a variable, it is not necessary to indicate the type of data it holds. For example: $var = 1;$var = "variable";$var = 1.00;$var = Array ();$var = new Object (); $var = 1;$var =

vararr = [1, 2, 3, 5, 5, ' 45 ', ' 45 ', 4, 1, ' 1 ', ' 2 '] for(vari = 0; I ) {Arr.push (i)//This adds 10000 entries to arr, allowing you to view the performance of each method later } /** Method One: Borrowing an array of results, the
