Php learning notes: uses the gd library to generate images and implement Random verification codes,
Note: I have commented on some basic code. Here, you can set the number of digits of the verification code and the required strings. With my comments, you can easily understand them.
Basic Ideas:
1. use mt_rand () to randomly generate a number to determine the string to be obtained and splice the string (think the generated verification code is a bit cr

It is true that, due to a serious security accident, I have to review this cURL library. How can I ensure that my requests are stable and reliable. When a failure occurs, I want to know the cause. Inform people immediately for timely communication, coordination, and repair.
Now, to ensure the stability and reliability of each request, the log function must be added. The Request Parameters and error cod

How to convert the codes of python and how to use python
Preface
I remember that when I got started, the problem of self-processing encoding conversion was often "Baidu: url Decoding, base64 encryption, hex ......", Or you can use a software called "xiaokui Multi-Function Conversion Tool" and then directly use the decoder function of Burpsuite. However, there are also some problems: Low online conversion efficiency (2/3 of search time), there are some
PHP source code for generating images online using QR codes
QR Code is becoming more and more popular. Here we will introduce the QR Code generated by PHP at both ends, one using the QR Code API opened by Google, and the other using the php qr Code open-source library.
1. Use the Google Chart API to generate a QR code Image
Google Chart API is a powerful API. Generating a QR code is only a small function. Here only introduces the QR code part, if you

A few notes about this code:1. Divide the data into smaller parts and then move it to the output stream for download to get the data.2. Specify Response.ContentType according to the file type you downloaded. (refer to this URL for Oschina to find the table of most file types: http://tool.oschina.net/commons)3. Remember to call Response.Flush () every time you finish writing Response4.
