Download file php shell_exec

Connect and share knowledge within a single location that is structured and easy to search. Ultimately I plan to have an input box on a page where I can enter a link and aria would download it. Note that the aria2c command I specified works well in the shell; and the directory I'm attempting to download to is set to ''.

PS: I prefer to use aria rather than the alternatives because it is multithreaded and it supports cookies. EDIT: aria2c was not referenced with a full path. I'll make the assumption that you are running PHP through a web server.

The Subversion error "svn: Can't recode string" can be caused by the locale being wrong. UTF-8' ;? From there, you can trim the command output etc.

For capturing stdout and stderr, when you don't care about the intermediate files, I've had better results with.

This combination destroys the string value returned from the call. I get binary garbage. Shell scripts that start with! A solution is to force a clean environment. This happens on both Linux and Windows. I finally isolated the problem to changes that Eclipse makes to the environment when debugging. The fix is to force the ini setting. If you don't need an ini then -n is sufficient. You may want to use a debug flag to control this behavior.

Empty string. It's interesting how shell command execution can get down to how nuanced one might need to be with string parsing. Other wise, it won't appear to be doing anything. Active 8 months ago. Viewed 4k times.
