user42609: How to read UID value in arduino uno to PHP language? 
before, thanks for a lot 


user33045: Use this library: https://github.com/rubberneck/php-serial
On GNU/Linux, you may need to be a member of the ‘dialout’ group. Ubuntu solves this problem by making its users members of every group, so you may not need to edit /etc/group
Once you have connected via a USB or USB-TTL cable (the latter will not force a reset upon connect), use a buffer to store all the reads, then parse them.
