Example #1 Creating a chdb file
<?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.
  
Example #2 Loading and looking up a chdb file
<?php
$chdb = new chdb('data.chdb');
$value1 = $chdb->get('key1');
$value2 = $chdb->get('key2');
echo $value1, PHP_EOL;
echo $value2, PHP_EOL;
?>
The above example will output something similar to:
value1 value2
