From the browser to the server side transmitted.

Request:

Data from the end of the transmission the browser to the server.

Visible :

Upload , occurred in the browser makes a request to the server process.

File , for the browser is concerned, is in the form of a special type of data only.

Browser data in the form of : two kinds of types.

1, the string type. ( Byte stream encoding)

2, file type. ( Binary-coded)

(Tip : file is the data in the form of a part).

Submit the form is, the browser automatically in the form of data, transmitted to the server, the file type will be included.

Server angle:

In an interview with the browser's request, handle the form in the data.

The different types of data (2 types), using a different approach:

1, string type is stored in the $ _POST variable in (memory)

2, file type data, stored in the temporary directory upload.

Form the time of submission : the browser will default view that data in the form is a string type (even with file file domain ) , through the form on the increased property tells the browser the type of data in the form not only has a string.

$file = 'x.y.z.png';

echo strrchr($file, '.');

// find the last occurrence of a substring in the string position, and the position to be taken from the end of the string.

Array_merge () array merge

array_unique () to remove the array elements in duplicate value

Rename the file:

Use original name. ( Duplicate names, special characters , does not have the logical meaning)

Named : uniqid ();

Uniqid () may generate a unique string prefix and allowed to set.
