## Installation
|
|
|
|
This package can be installed as a [Composer](https://getcomposer.org/) dependency.
|
|
|
|
```bash
|
|
composer require amphp/postgres
|
|
```
|
|
|
|
## Requirements
|
|
|
|
- PHP 7.0+
|
|
- [ext-pgsql](https://secure.php.net/pgsql) or [pecl-pq](https://pecl.php.net/package/pq)
|
|
|
|
Note: [pecl-ev](https://pecl.php.net/package/ev) is not compatible with ext-pgsql. If you wish to use pecl-ev for the event loop backend, you must use pecl-pq.

```php
|
|
Amp\Loop::run(function () {
|
|
/** @var \Amp\Postgres\Pool $pool */
|
|
$pool = Amp\Postgres\pool("host=localhost user=postgres dbname=test");
|
|
|
|
/** @var \Amp\Postgres\Statement $statement */
|
|
$statement = yield $pool->prepare("SELECT * FROM test WHERE id = :id");
|
|
|
|
/** @var \Amp\Postgres\ResultSet $result */
|
|
$result = yield $statement->execute(['id' => 1337]);
|
|
while (yield $result->advance()) {
|
|
$row = $result->getCurrent();
|
|
// $row is an array (map) of column values. e.g.: $row['column_name']
|
|
}
|
|
});
|
|
```
