Definition: Select.php is a PHP function used to retrieve data from a database. It selects specific columns in an array or tuple based on SQL (Structured Query Language) query parameters. For example, it retrieves a single row of data with the following structure:
```sql
SELECT
FROM users LIMIT 1;
```
The `LIMIT` statement limits the number of rows returned by the query to one, ensuring that only the first element of each tuple is retrieved.
The word 'select' comes from the Greek words "συν(λήξη) σύνθεκρία" which means to choose, select, or make a choice. So in this context, `SELECT` refers to selecting specific data or information from a database table.
Detailed definition: Select.php is an API that allows you to query and retrieve data from your MySQL database through a SQL (Structured Query Language) query string, allowing for easy data manipulation and filtering.
