(PECL chdb >= 0.1.0)

chdb_create — Creates a chdb file

### 説明

void chdb_create ( string `$pathname` , array `$data` )

chdb_create() creates a chdb file containing the specified key-value pairs.

> 注意: chdb files are not portable across little-endian and big-endian environments. Except for that, they are portable across different architectures. Also compatibility across different versions of chdb is not guaranteed.

### パラメータ

`pathname`

  The name of the file to create.

  If a file with the same name already exists, it is overwritten.

`data`

  An array containing the key-value pairs to store in the chdb file.

  Keys and values are converted to strings before being written to the file, as chdb only support the string type. Note that binary strings are supported as well, both as keys and values.

### 返り値

値を返しません。

### エラー / 例外

Throws an exception in case the chdb file hasn't been successfully created.

### 例

例1 chdb_create() example

`<?php
$data = array(
'key1' => 'value1',
'key2' => 'value2',
// ...
);
chdb_create('data.chdb', $data);
?>`

The above example will generate a chdb file named data.chdb and containing the key-value pairs defined in $data.
