The examples in this article describe how PHP compares similar strings. Share to everyone for your reference. The specific analysis is as follows:
This compares the similarity of two strings through the Similar_text function of PHP.
$word 2compare = "stupid";
$words = Array (
' stupid ', '
Stu and PID ',
' hello ',
' foobar ',
' stpid ',
' upid ',
' Stuuupid ',
' sstuuupiiid ',
);
while (the list ($id, $str) = each ($words)) {
Python's dict is easy to use, you can customize the key value and access it by subscript, as shown in the following example:
Copy Code code as follows:
>>> d = {' Key1 ': ' value1 ',
... ' Key2 ': ' value2 ',
... ' Key3 ': ' Value3 '}
>>> print d[' Key2 ']
value2
>>>
Lambda expressions are also useful, as the following examples are:
Copy Code code as follows:
>>> f = Lambda x:x**2
>>> print F (2)
4
>>>
The combination of the two can a
We do unit test NUnit, there's an assertion that assert.throws works, but when we use mstest you need to write this:
Copy Code code as follows:
[TestMethod]
[ExpectedException (typeof (ArgumentNullException))]
public void Writetotextfile ()
{
Pdfutility.writetotextfile ("d:\\aca.pdf", null);
}
Now let's expand it and implement a similar function, adding a class with the following code:
Copy Code code as follows:
This article describes the JS+CSS to achieve a similar QQ friends and blacklist effect of the tree-type menu. Share to everyone for your reference. Specifically as follows:
Today's introduction of the menu is the best ah, but there are some of the icons lost, the path is still there, really want to use a friend of their own production of two folding menu icon by path to go up on the line, this menu is to imitate the menu features QQ panel, many frien
The example of this article tells JS to achieve a similar animate animation effect in jquery. Share to everyone for your reference. The specific analysis is as follows:
This example can achieve the mouse move, the first width changes, then height changes, the final transparency changes, mouse out, and then turn back the effect.
Point one:
Startrun (OBJ,ATTR,TARGET,FN)
box.onmouseover = function () {
startrun (box, width, 200,function () {

JQ's Extend () method can conveniently implement the extended object method, the syntax is as follows: $.extend (OBJ1,BOJ2,OBJ3);
Now to achieve is: the original JS implementation of replication objects, extended objects, similar to the JQ in the Extend () method, specific examples are as follows:Existing 3 objects literal:
var o1={hello:1,old:555},
O2 = {
abc:55555555,
hello:2,
fun:function () {
alert ()}
} ,
o3={third:9999};
To achieve

The example in the previous blog can only handle a server to a client situation, today modified a version that can support a server to multiple client. The implementation is that the server throws a single action into a thread, the client is similar to each received a data, a thread to do their own logic. This looks a bit like a socket into a.
