shell-exec

问题 This question already has an answer here : PHP shell_exec wait for script to finish? [duplicate] (1 answer) Closed 4 years ago . I have a PHP script that queries a database for a list of jobs to be done and fires off other PHP scripts based on what it finds in the database (basically a process queue).

问题 So I'm planning on using shell_exec() to handle running a php script that sends an email. It's all working great, but I was just slightly concerned about the security implications of only using FILTER_VALIDATE_EMAIL to ensure injection can't occur. So, for example, I will be using something simlilar to this: $email=$_POST['email']; if(!filter_var($email, FILTER_VALIDATE_EMAIL)) { echo 'Nope ...'; } else { shell_exec("/usr/bin/php /var/www/mysite/includes/sendemail '" . $email . "'" > /dev

问题 Trying to figure this out. I am trying to execute a perl script within php, using shell_exec() like so: <?php $output=shell_exec("./tst.pl > test.txt"); //$output=shell_exec("./tst.pl"); echo $output; ?> It will not write output to a file using ">" filename.txt. It will work if I execute without directing it to a filename as I can confirm this with echo. Does this have to do with using ">"? Permissions should be fine as I am able to run the same perl script on command line and direct to file.

问题 I am trying to generate a PDF from HTML using PHP. I am running Mac OS X as my development environment although I would like this code to run on a production linux server.
