How do i call bash script function using exec function by passing parameter in php?

Question

I have created a bash script that install magento in a cpanel. but i have a problem regarding the exec function.

$function_path = Mage::getBaseDir()."/media/installer/function.sh"; 
exec("$function_path $db_host $db_name $db_user $db_pass $url $ad_user $ad_pass $ad_email");

In the exec function I am passing all the parameters that the shell script will need to create a Magento databse and install it. This is the bash shell script code written in the function.sh file

#!/bin/bash

magento_detail $dbhost $dbname $dbuser $dbpass $url $admin_username $admin_password $admin_email
function magento_detail()
{

stty erase '^?'

echo "To install Magento, you will need a blank database ready with a user assigned to it."

echo -n "Do you have all of your database information"

dbinfo = "y"
echo $dbinfo 
if [ "$dbinfo" -eq 'y' ]
then
    echo "Database Host (usually localhost) : $dbhost "

    echo "Database Name : $dbname "

    echo "Database User : $dbuser "

    echo "Database Password : $dbpass "

    echo "Store Url : $url "

    echo "Admin Username : $admin_username "

    echo "Admin Password : $admin_password "

    echo "Admin Email Address : $admin_email "

    echo -n "Include Sample Data? (y/n) "

    echo sample = "y"

    if [ "$sample" -eq "y" ];

        exit
    fi
else
    echo "Please setup a database first. Don't forget to assign a database user!"

    exit
fi
}`

My problem is that it doesn't execute all commands of the script and directly goes to the last step of if condition and prints "Please setup a database first. Don't forget to assign a database user!". Can anyone tell my whey the script is skipping the if part and directly going to the else part?

Answer 1

The problem is with this line i suppose
"$dbinfo" -eq 'y'

you can't check strings with -eq, it is just for unary statements.
replace with
"$dbinfo" == "y"

and it should work.
