**[Documentation Site](https://smi2.github.io/phpClickHouse/)**
PHP client for [ClickHouse](https://clickhouse.com) — fast, lightweight, no dependencies beyond ext-curl.
## Features
- Sync & async (parallel) SELECT queries
- [Native query parameters](doc/native-params.md) — server-side `{name:Type}` binding, SQL injection impossible
- [Rich type system](doc/types.md) — Boolean, Int64, Decimal, UUID, IPv4/IPv6, DateTime64, Date32, Map, Tuple
- Bulk inserts: arrays, CSV files, streams
- [Generators](doc/generators.md) — memory-efficient iteration for large resultsets
- HTTP compression (gzip) for inserts
- [Parameter bindings](doc/bindings.md) & SQL templates
- [Per-query settings](doc/per-query-settings.md) — override ClickHouse settings per request
- [Cluster support](doc/cluster.md) — auto-discovery, health checks, replicas
- [Streaming](doc/streaming.md) read/write with closures
- [Progress callbacks](doc/progress.md) for SELECT and INSERT
- [Structured exceptions](doc/exceptions.md) — ClickHouse error name, query ID
- Sessions, write-to-file, [INSERT statistics](doc/summary.md)
- HTTPS, SSL CA, IPv6 support
- Multiple auth methods (none, header, basic auth, query string)
## Requirements
- PHP 8.0+
- ext-curl
- ext-json

## Installation
```bash
composer require smi2/phpclickhouse
```
## Quick Start
```php
$db = new ClickHouseDB\Client([
'host' => '127.0.0.1',
'port' => '8123',
'username' => 'default',
'password' => '',
]);
$db->database('default');
$db->setTimeout(10);
$db->setConnectTimeOut(5);
$db->ping(true); // throws exception on failure
```
### Select
```php
$statement = $db->select('SELECT * FROM my_table WHERE id = :id', ['id' => 42]);
$statement->rows(); // all rows
$statement->fetchOne(); // first row
$statement->count(); // row count
```
### Native Query Parameters
```php
// Server-side typed binding — SQL injection impossible at protocol level
$result = $db->selectWithParams(
'SELECT * FROM users WHERE id = {id:UInt32} AND name = {name:String}',
['id' => 42, 'name' => 'Alice']
);
```
### Insert
```php
$db->insert('my_table',
[
[time(), 'key1', 100],
[time(), 'key2', 200],
],
['event_time', 'key', 'value']
);
```
### Generator (large resultsets)
```php
// Memory-efficient — one row at a time, no OOM
foreach ($db->selectGenerator('SELECT * FROM huge_table') as $row) {
processRow($row);
}
```
### Write (DDL)
```php
$db->write('CREATE TABLE IF NOT EXISTS my_table (id UInt32, name String) ENGINE = MergeTree ORDER BY id');
$db->write('DROP TABLE IF EXISTS my_table');
```
