PHP File upload failed

Using the OSX system, using Mamp Pro as a virtual server, and using PHP as the backend language for file uploads, copying files from the Temp folder is

Move_uploaded_file

The code is as follows:

1 if($_files[' file '] [' ERROR ']>0){2echo ' File Error ';3}Else{4echo ' upload: '. $_files[' file ' [' name ']. ' <br> ';5echo ' type: '. $_files[' file ' [' type ']. ' <br> ';6echo ' Size: '. $_files[' file ' [' Size ']. ' <br> ';7Echo ' stored in: '. $_files[' file ' [' Tmp_name ']. ' <br> ';8     if(File_exists ("upload/". $_files[' file '] ["name"]))9           {Tenecho $_files[' file ' ["Name"]. "already exists."; One           } A         Else -           { -Move_uploaded_file ($_files[' file '] ["Tmp_name"], the"Upload/". $_files[' file ' ["Name"]]); -echo "Stored in:". " /applications/mamp/htdocs/learnphp/upload/". $_files[' file ' ["Name"]]; -           } -}

Operation Error:

[23-mar-2016 22:01:39] PHP Warning: In/applications/mamp/htdocs/learnphp/upload.php to line   18[23-mar-2016 22:01:39] php Warning:  move_uploaded_file () [<a href= ' function.move-uploaded-file ' >function.

The main error is

Failed to open Stream:permission denied

This means that PHP does not have folder write permissions, because only owner has write permissions. We need to change the owner of this folder to httpd owner:

$ ps aux | grep httpd

The result is:

The first column is _www, so the owner of httpd is _www.

Next, modify the owner of the folder:

That's it! Let's verify now:

Look at the owner of this folder:

Go to the File parent directory:

$ cd/applications/mamp/htdocs/learnphp/

To view the owner of a subdirectory:

The result is:

Drwxr-xr-x  3 Yellow  admin  102  3 20:27 files-rw-r--r--  1 Yellow  admin  277  3 19:42 index.htmldrwxr-xr-x  4 _www    admin  136  3 23:07 upload-  rw-r--r--  1 Yellow  admin  792  3 10:50 upload.php-rw-r--r--  1 Yellow  Admin  275  3 21:10 welcome.php

We can see that the owner of the upload folder is already _www, but then the user will be prompted to enter the administrator password when they modify the folder in the normal operation.
