I am trying to convert one of my shell scripts to php, but not sure how to set a particular variable. Currently, this is what I have in my shell script:

MYSQL="$(which mysql)"

How can I code this in php?

I tried the following, but just got this: which mysql
<?php
  $mysql="which mysql";
  echo $mysql;
?>

Open in new window

Correct.  In your original example, It looks like
MYSQL <- is a variable being assigned information
"$(which mysql)" <-- is a string that contains the address of the mysql server.

so
$mysql = "which mysql"
would accomplish the same thing.  Now if $(which mysql) is a function returning a string then the statement should be
$mysql = which mysql

<?php

 $mysql = shell_exec('which mysql');
 echo $mysql

?>

Open in new window
