What does id 1 mean in php?
In php, $_ request and $_ post, $_ get are used to accept form data, what is the difference between them at that time, and when is the best time to use that one.
1. The differences and characteristics between $_ request and $_ post, $_ get $_ REQUEST [] has the function of $_ POST [] $_ GET [], but $_ REQUEST [] is slow. All data submitted through the post and get methods can be obtained through the $_ REQUEST array
Second, the differences and characteristics of $_ post and $_ get
1. Get obtains data from the server, and post transmits data to the server.
2. Get adds the parameter data queue to the URL referred to in the ACTION attribute of the submitted form, and the value corresponds to each field in the form, which can be seen in URL. Through the HTTP post mechanism, post transmits each field in the form together with its contents in the HTML HEADER to the URL address referred to by the ACTION attribute. The process is not visible to the user.
3. For get mode, the server uses Request.QueryString to obtain the value of the variable, and for post mode, the server uses Request.Form to obtain the submitted data.
4. The amount of data transmitted by get is small and cannot be greater than 2KB. Post transmits a large amount of data and is generally regarded as unrestricted by default. But in theory, the maximum amount of IIS4 is 80KB and 100KB in IIS5.
5. The security of get is very low, while that of post is high.
For example: mypage?id=1 this is the GET way to pass values, you can use $_ request and $_ get to accept the value.
