The PHP script shown is designed to connect to a MySQL database and execute a query. Below is a line-by-line explanation of the code:1. `Cannot connect to DB\n");`: If the connection fails, the script stops executing and outputs "Cannot connect to DB."5. `$query = "SELECT fname from dreamhome.Staff where sex='FF' and salary > 20000";`: Defines an SQL query to select the first name from the `Staff` table in the `dreamhome` database where the sex is 'FF' (female) and the salary is greater than 20000.6. `$result = mysqli_query($con,$query);`: Sends the SQL query to the database and stores the result.7. `if($result) {`: Checks if the query execution was successful.8. `if (mysqli_num_rows($result)>0)`: Checks if the query returned any rows.9. `echo "Monkey\n";`: If rows are returned, it outputs "Monkey."10. `else`: If no rows are returned from the query,11. `echo "Tiger\n";`: It outputs "Tiger."12. `}`: Closes the first `if` block.13. `else`: If the query execution fails,14. `echo "Dog\n";`: It outputs "Dog."15. `}`: Closes the `else` block.16. `mysqli_close($con);`: Closes the database connection.17. `?>`: Ends the PHP script.### Explanation- The code first attempts to connect to the database.- If successful, it queries to find any female staff with a salary greater than 20000.- If such records are found, it outputs "Monkey."- If no such records are found, it outputs "Tiger."- If the query itself fails, it outputs "Dog."This code tests basic database connectivity and query execution, displaying different strings based on the success of each operation.

PHP is among the most widely used open source scripting language.

Please refer to the table in the dreamhome database. If the connection is successful and we run the following PHP codes on obi.kean.edu, which statement. is TRUE? 1 Cannot connect to DB\n"); 5 $query = "SELECT fname from dreamhome. Staff where sex= 'FF' and salary > 20000"; 6 $result = mysqli_query($con, $query); 7 if($result) { 8 9 10 11 if (mysqli_num_rows($result)>0) echo "Monkey\n"; else echo "Tiger\n"; 12} 13 else 14 15 16 mysqli_close($con); 17 ?> echo "Dog\n";

A database for inventory and transaction of Apple store has been developed. There are three tables in this database – Inventory, Transaction, Inventory_history. You can use the following script to create the tables. create table Inventory ( itemid varchar(20) primary key, name varchar(30), price decimal(6,2), quantity int ); create table Transaction ( transid int auto_increment primary key, itemid varchar(20), quantity int, time datetime, foreign key (itemid) references Inventory(itemid) ); create table Inventory_history ( id int auto_increment primary key, itemid varchar(20), action varchar(20), oldprice decimal(6,2), time datetime, foreign key (itemid) references Inventory(itemid) ); 2) Create a trigger “change_quantity” on table “Transaction”. The trigger is fired after a row is inserted in table “Transaction”. After a row is inserted in table “Transaction”, update the “quantity” in table “Inventory”. For example, if 3 iWatch are sold, then the quantity of iWatch in table…
