Download the PHP package jpi/query without Composer

Query

USE AT YOUR OWN RISK!

I would advise against using this on production applications...but feel free to use in your own personal / demo / experimental projects.

A simple library to make querying a database easier it works as a middleman between the application and a database.

This has been kept very simple stupid (KISS), other than type errors from PHP there is no validation, it will assume you are using it correctly. So please make sure to add your own validation if using user inputs in these queries.

Dependencies

• PHP 8.0+
• Composer
• PHP PDO
• MySQL 5+
• jpi/database v2

Installation

Use Composer

Usage

To create an instance, you will need an instance of \JPI\Database (if unfamiliar you can read about that here) which is the first parameter, and the database table name as the second parameter. The same instance can be used multiple times as long as it's for the same database.

Action Methods:

These are the methods to call to end with select, count: int, insert($values array): int|null, update($values array): int & delete: int, all are pretty self-explanatory.

Builder methods

These are all fluent methods, so you can chain them together.

• table(string $table, string|null $alias): if you want to change to another table or didn't set when creating the instance
• column(string $column, string|null $alias): will select all columns if not set
• where:
  • you can pass in the whole clause using the first parameter
  • or you can pass column, expression and value separately
• orderBy(string $column, bool $ascDirection = true)
• limit(int $limit, int|null $page)
• page(int): used to change the offset, only used if limit set

Examples

Assuming a \JPI\Database\Query\Builder instance has been created for the users database table and set to a variable named $queryBuilder.

select

This has 4 return types depending on how you use it:

• if you've set limit of 1 this will return an associative array of key (column) value pairs or if not found then null
• if paged \JPI\Database\Query\PaginatedResult
• else \JPI\Database\Query\Result

PaginatedResult & Result work like a normal array just with some extra methods, see https://github.com/jahidulpabelislam/utils?tab=readme-ov-file#collection for more details.

count

As the name implies this method will just return the count as an integer.

For obvious reasons only the table & where builder methods are supported for this action.

insert

This method will just return the id of the row created unless it fails then null.

Only the table builder method is supported for this action.

update

This method will return the count of how many rows have been updated by the query.

column & page builder methods aren't supported for this action.

delete

This method will return the count of how many rows have been deleted by the query.

column & page builder methods aren't supported for this action.
