In PHP you can use simple Perl to execute a Perl script or you can use exec function. Passing variable from PHP to Perl is easy. Yea we are retrieving those values from PHP to Perl. So in that case small alteration in your Perl script like below. $data = str_replace("Content-type: text/plain","",$perl_result) Įither you can pass port number and baudrate from PHP to Perl or you can set it in Perl script, but its better to passing values bcoz some device port may be different. Header('Access-Control-Allow-Origin: *') you have to call the Perl script from PHP using following methods. Yea with the help of Perl script we can implement serial port data reading within PHP. Reading Serial port data using PHP under Windows ? Ok now I have a Perl solution for reading serial port data on Windows. If you’re in Linux OS you can use my Read Serial Port with PHP script for reading serial port, my intention is to do with PHP, but on Windows PHP can’t read serial port data, So I choose Perl. Yea read serial port data using Perl is done !. In my case I connected weigh machine with USB port and my port number is COM3. Once the device is connected you can read the out put in CLI. Save the above script as file and run it using localhost or CLI. } while ($numChars close || die "failed to close" $PortObj->read_char_time(5) # avg time between read char $PortObj->read_interval(100) # max time between read char (milliseconds) # $PortObj->save($Configuration_File_Name) $PortObj->write_settings || undef $PortObj $PortObj->error_msg(1) # prints major messages like "Framing Error" $PortObj = new Win32::SerialPort ($port) || die "Can't open $port: $^E\n" # If you miss this line then it will show "malformed header from script" error. # The below line tells the browser, that this script will send html content. # The above line is perl execution path in xampp also the Port is set to COM3 that you have to check once you connect the serial device. #PHP SERIAL PORT WINDOWS CODE#The following code first line you should to your Perl.exe file. so you can run the Perl script via browser. If you’re using Xampp it will come with Apache PHP Mysql and Perl so there is no need of additional Perl setup. you just need to make sure which directory the Perl get installed, and that you have to specify at the top of the line in the script. Read serial port data using perl is just about few lines of code. ![]()
