Hey there.
I have a PHP script executing multiple C programs (which have been placed in /usr/local/bin/) using 'backticks', like so:
$data= `sudo CProg`;
When the C program has executed, it will print to console the values:
5,75
The PHP is then meant to grab the comma-separated values, then 'explode' them and save each into corresponding values:
$dataValues = array_map('trim',explode(",", $data));
$valueOne = $dataValues[0];
$valueTwo= $dataValues[1];
echo "<br>Value 1: $dataValues[0] <br> Value 2: $dataValues[1]<br>";
The problem is the PHP only seems to grab the commas with the echo resulting in only ' , ' being displayed. I know for a fact that this script and program should work as it was working before I had to fully rebuild my Linux (I know, I should have had a backup).
EDIT for reference: I had forgotten to give www-data the ability to execute programs using sudo
