如何使用exec函数通过在php中传递参数来调用bash脚本函数？

我创建了一个bash脚本，可以在cpanel中安装magento。但是我有一个关于exec函数的问题

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

在exec函数中，我传递shell脚本创建并安装Magento数据库所需的所有参数。这是在function.sh文件中编写的bash shell脚本代码

#!/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" ];
    then
        echo
        echo "Now installing Magento with sample data..."

        echo
        echo "Downloading packages..."

我的问题是，它没有执行脚本的所有命令，而是直接进入的最后一步，如果条件并打印“请先设置数据库。”。别忘了分配一个数据库用户！“。有人能告诉我脚本跳过了if部分而直接转到了else部分吗？

我想问题出在这一行

“$dbinfo”-等式'y'

不能用-eq检查字符串，它只用于一元语句。
替换为

“$dbinfo”==“y”

---

而且它应该可以工作。

我想问题在于这条线

“$dbinfo”-等式'y'

那么您到底在执行shell的什么？请发布您的具体exec字符串
