It consumes energy and can operate and perform work. It is used to replace human labor, perform energy conversion, information processing, and produce useful work. Machines have been present throughout human history. But the real "machine" in modern times was gradually invented after the Western Industrial Revolution.

This conversion is a compressed mapping, that is, the space of hash values ​​is usually much smaller than the space of inputs. Different inputs may hash into the same output, so it is impossible to uniquely determine the input value from the hash value. Simply put, it is a function that compresses a message of any length into a message digest of a fixed length. HASH function (computer algorithm field)

So, today we will introduce to you the verification class library, the primary measure to ensure PHP security. Data verification is the most important habit you may adopt. And when it comes to input, it's very simple: don't trust the user. When validating data to secure PHP, remember that it's often easier to design and validate the values ​​your application allows than to protect against all unknown values.

When validating data to secure PHP, remember that it's often easier to design and validate the values ​​your application allows than to protect against all unknown values. General validation tips that apply to various types of validation data are listed below: 1. Use values ​​from the whitelist2. Always re-validate limited options3. Use the built-in escape function4. Verify that the correct data type (such as a number)The value in the white-listed value (White-listed value) is the correct value , as opposed to an invalid blacklist value (Black-listed value). The difference between the two is that typically when validating data, the list or range of possible values ​​is smaller than the list or range of invalid values, many of which may be unknown or unexpected values.

Caching query results can greatly improve script execution time and resource requirements. Caching SQL query results also allows you to post-process the data. If you use file caching to store the output of all scripts (the normal method of HTML is very resource-intensive and adversely affects the performance of the script). This can only be reconciled by the large amount of returned data obtained and the location of the database server. .Although continuous connections can improve the load when connecting to the database, it consumes very memory resources. If a large amount of data is obtained, the entire storage time will be very short. Therefore, the StashPHP caching library is specifically designed to solve this caching problem in PHP.

Compared with libraries such as cURL, it has a simple, easy-to-use and friendly API and does not depend on cURL. It supports methods such as HEAD, GET, POST, PUT, DELETE and PATCH, and can basically satisfy any form of HTTP request. Requests does not depend on any extensions outside the PHP standard library. The only requirement is the PHP5.2 version. But if PHP's cURL is available, Requests will use it first, otherwise it will use socket.
