Calling MySQL exe using PHP exec doesn't work

Question

I have an extremely simple script with PHP exec, calling mysql command:

  $dbhost = \'localhost\';
  $dbuser = \'root\';
  $dbpass

This was happening to me too even on Ubuntu. The problem was that i was doing the following code:

$mysql = shell_exec("sudo which mysql");
$cmd = "$mysql --host=$host --user=$user --password=$pass -D $dbname -e 'source $base_sql_file'";
exec($cmd, $output, $retvar);

Only a slight detail was missing... the shell_exec returns the output with trailling characters. When executing the command i was getting a MySQL error 127 (Record is crashed).

The solution was simple: add a trim function to shell_exec :)

$mysql = trim(shell_exec("sudo which mysql"));
$cmd = "$mysql --host=$host --user=$user --password=$pass -D $dbname -e 'source $base_sql_file'";
exec($cmd, $output, $retvar);
