Question
I've got a PHP command line program running. And I want to connect to a mysql shell straight from PHP. I've done this before in Python using os.execvp But I can't get the same thing to work in PHP.
I've tried the following functions:
- system
- passthru
- exec
- shell_exec
example:
system('mysql -u root -pxxxx db_name');
But they all seem to wait for mysql to exit and return something. What I really want is for PHP to launch the mysql shell and then exit it self. any ideas?
Solution
If you want shell commands to be interactive, use:
system("mysql -uroot -p db_name > `tty`");
That will work for most cases, but will break if you aren't in a terminal.
OTHER TIPS
Give MySQL a script to run that's separate from the PHP script:
system('mysql -u root -pxxxx db_name < script.mysql');
In addition to what acrosman said, you can also use the -e
switch to pass SQL from the command line.
$sql = ".....";
system("mysql -u root -pxxxx db_name -e \"$sql\"");
Also, I hope your not actually connecting to the database as root from a PHP application.
