I used a notebook, which is just happening. The keyboard input in my notebook is out of order, and all the letters are converted into numbers. I thought it was a computer problem at first, and I restarted it three times.After studying for a while, I found that this is not a problem because I accidentally opened the keyboard of my notebook. If you do not dare to enjoy the solution exclusively, we will share

This article mainly introduces PHP to do program development process, we will often in the login interface or comment interface to do some four-digit verification code, the need for friends can refer to the next So we know that a simple four-bit digital verification in PHP can be used with Rand (1000,9999), but how do we write a function if we want to get a random four-digit number of letters and numbers?

PHP Implementation of random numbers, letters of the Verification Code Customizable to generate CAPTCHA text size, number, interference items, etc., you can also customize the font of text validation ... Nonsense not much to say, directly on the code: 2, testcaptcha.php The above is the whole content of this article, I hope that everyone's learning has helped, more relevant content please pay attention

Verification code supports numbers, letters, Chinese characters, and mixing Width = $ width; $ this-> height = $ height; $ this-> codeNum = $ codeNum; $ this-> codeType = $ codeType; $ this-> fontSize = $ fontSize; $ this-> fontType = $ fontType; $ this-> codeStr = $ codeStr; $ this-> strNum = strlen ($ this-> codeStr)/3-1; $ this-> imageType = $ imageType; $ this-> checkCode = $ this-> getCheckCode ();} //

The front core and IX logo are exactly the same as the previous generation and do not introduce more.First "4": Represents the Intel Core fourth generation processor;Second "5" "6" "7" "8" "9": Represents the processor level, the higher the number of the performance level;Third "3" "5" "0": this is basically the corresponding core graphics card model, where "3" for the high-performance processor with HD 4600, "5" for the core graphics card using Iris 5000, 5100 or Pro5200, while "0" is HD 4600;F

There are 26 letters {A-Z} and 10 numbers {0-9} If you want to generate 8-bit characters, the case-sensitive, This arrangement is (26+26+10) 8 times Square = 218,340,105,584,896, which 218 trillion But adjacent cannot have two or more of the same as {a1b2cc90, this character appears two times CC} Can such data be generated in PHP? If generating a single text data should be less likely to be cut into many pa

When a block element that defines the width is filled with only English letters or numbers, both IE and FF support large containers and will not automatically wrap.In addition, when a number or an English character carries a Chinese character, it will wrap the line from the Chinese character, but the pure Chinese character can wrap the line automatically. How can this problem be solved? Let's take a loo
