Thanks for your interest. I figure it out. A colleague will run a php file on the server, so I had to do in in another way. Reading in the forum, looking for solutions I found ideas on how to make it done. So I end with this:
#include <Array.au3>
#include <File.au3>
#include <MsgBoxConstants.au3>
#include <InetConstants.au3>
#include <WinAPIFiles.au3>
MarkCompleted()
Func MarkCompleted()
; List all the files and folders in the desktop directory using the default parameters.
Local $aFileList = _FileListToArray(@DesktopDir &"\" &@YEAR &"_"& @MON &"_"& @MDAY & "_picpic_orders", "*.txt")
If @error = 1 Then
MsgBox($MB_SYSTEMMODAL, "", "Path was invalid.")
Exit
EndIf
If @error = 4 Then
MsgBox($MB_SYSTEMMODAL, "", "No file(s) were found.")
Exit
EndIf
For $i= 1 to 18
Local $sString = StringLeft($aFileList[$i], 4) ; Retrieve 5 characters from the left of the string.
InetGet("https://hellopicpic.com/set_pic_orders_completed.php?token=ygtV2bMh23uJ7f6s&id="&$sString & @CRLF, $INET_FORCERELOAD, $INET_DOWNLOADBACKGROUND)
Next
EndFunc ;==>MarkCompleted
