Creates a chdb file

Descrierea

chdb_create ( string $pathname , array $data ) : bool

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

Notă:
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.

Parametri

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.

Valorile întoarse

Întoarce valoarea TRUE în cazul succesului sau FALSE în cazul eșecului.

Erori/Excepții

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

Exemple

Example #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.
