PHP multi-file Upload analysis. PHP multi-file Upload I personally understand that multi-file upload is a basic application in PHP. I would like to give you a detailed introduction here. I have a limited level. please give more comments. I personally understand that multifile upload is a basic application in PHP. I would like to introduce the relevant knowledge to you here. I have a limited level. I would like to provide more comments. Everyone makes progress together.
Add [] to the name of the input tag FILE type of the html file to create an array in the html file. for example, the name is pictures, the multi-file reference name is pictures [], and the instance is as follows:
// Example in the manual.The methods for creating arrays using HTML files are described as follows:
To make yourPHP receiving File:
print_r($_FILES);
?>Save it as UPLOAD. PHP and run the above HTML to select a file to UPLOAD. for example, if the file name is Thumbs. db, click View and source code in IE browser ". Shown as follows:
Array
(
[Pictures] => Array
(
[Name] => Thumbs. db // original file name
[Type] => application/octet-stream // file type
[Tmp_name] => D: EasyPHP \ tmpphp64.tmp // temporary storage directory and file name
[Error] => 0 // error code 0 indicates that the upload is successful.
[Size] => 23040 // file size
)
) According to this information, combined with the usage of the above $ _ FILES, you should be able to understand more deeply.
Next let's take a look at multifile Upload. The three file names are FILE1.TXT, FILE2.TXT, and FILE3.TXT respectively, and then use PRINT_R output to view their structure:
HTML file code:
PHP receiving file code:
print_r($_FILES);
?>View source files:
Array
(
[Pictures] => Array
(
[Name] => Array
(
[0] => file1.txt
[1] => file2.txt
[2] => file3.txt
)
[Type] => Array
(
[0] => application/octet-stream
[1] => application/octet-stream
[2] => application/octet-stream
)
[Tmp_name] => Array
(
[0] => D: EasyPHP \ tmpphp47.tmp
[1] => D: EasyPHP \ tmpphp48.tmp
[2] => D: EasyPHP \ tmpphp49.tmp
)
[Error] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
[Size] => Array
(
[0] = & gt; 94289
[1] => 65536.
[2] => 102400.
)
)
)
If the FILES named/file1.txt and/file2.txt are submitted, the value of $ _ FILES ['pictures'] ['name'] [0] will be file1.txt, the value of $ _ FILES ['pictures'] ['name'] [1] is file2.txt. When 'file2.txt '] ['size'] [0] will contain the size of the file file1.txt, and so on.
Upload multiple files is a basic application in PHP. I would like to introduce the relevant knowledge here. I have a limited level. please provide more comments. Everybody one...
