10-10: Add clarity to your error message for better debugging.
Appending the raw$database->connect_errordirectly to “Error! connection failed” may be sufficient, but consider adding punctuation or whitespace. For instance:die("Error! Connection failed: " . $database->connect_error);

Confirm environment consistency for new DB server and DB name.
Switching from"db"to"localhost"and"edoc"to"sql_database_edoc"may break code outside of Docker-like setups or if the new database name does not exist. Ensure that these changes align with your local/production database environment and that"sql_database_edoc"is set up accordingly.You can verify by checking the actual DB names and environment variables with this script:
🏁 Script executed:
#!/bin/bash # Check if the "sql_database_edoc" DB is present and "localhost" is accessible. # List databases mysql -h localhost -u root -p -e "SHOW DATABASES;" # Verify the presence of 'sql_database_edoc' in the listLength of output: 148
Action Required: Verify New Database Connection Settings
Please ensure that your updated database connection parameters in
connection.php(i.e.,"localhost","root", empty password, and"sql_database_edoc") are consistent with your intended environment. The automated verification script failed because themysqlcommand was not found. Kindly verify manually that:
- The MySQL client is installed and accessible in your environment.
- The
"sql_database_edoc"database exists and is correctly configured for your local/production setups.patient/settings.php (1)

Reintroduce parameterized queries to avoid SQL injection.
By constructing the query with $useremail directly in the string, you risk SQL injection if $useremail is not fully trusted. It’s safer to use parameter binding:

Restore prepared statements to ensure secure user lookups.

String Interpolation of $spe
$spcil_res= $database->query("select sname from specialties where id='$spe'"); is susceptible to injection if $spe is untrusted.
