This Service is used to abstrain the use of the BigQuery from Google using php language

Dependencis

To use this Service you should first install the offial library from Google and our google-bigquery-service:

$ composer require google/cloud-bigquery
$ composer require valdiney/google-bigquery-service

Inicial usage

To start, you should firts create a dataset and a table:

require_once 'vendor/autoload.php';

# Instanciating the object to be used in the our application
# You should pass the path and name of your json file with yours credensials downloaded from google acount
$bigQuery = new GoogleBigQueryService\BigQueryService("AlarmaAe-b01ab0a3aa4c.json");

# Struturing the schema of the table. 
$schema = [
	[
	  "name" => "name",
	  "type" => "string"
	],
	[
	    "name" => "age",
	    "type" => "integer"
	]
];

# Creating the dataset and the table
$bigQuery->createSchema("datasetName", "tableName", $schema);

Insert data

after creating the dataset and the table, we ready to insert data:

require_once 'vendor/autoload.php';

# Instanciating the object to be used in the our application
$bigQuery = new GoogleBigQueryService\BigQueryService("AlarmaAe-b01ab0a3aa4c.json");

# The name of dataset
$bigQuery->setDatasetId("datasetName");

# The name of table
$bigQuery->setTable("tableName");

# Inserting data in our table. You shoul pass an associative array to the insert method
$bigQuery->insert(["name" => "Nicolas tesla", "age" => 87]);

Selecting data from our table

To select data is very simple. You just need pass your SQL query to the query method.
You need pass the especial string "{table} " between the SQL query. This especial string will be repleced into the class in a format that the BigQuery understand!:

require_once 'vendor/autoload.php';

# Instanciating the object to be used in the our application
$bigQuery = new GoogleBigQueryService\BigQueryService("AlarmaAe-b01ab0a3aa4c.json");

# The name of dataset
$bigQuery->setDatasetId("datasetName");

# The name of table
$bigQuery->setTable("tableName");

# Your SQL query
$collections = $bigQuery->query("SELECT * FROM {table}");

foreach ($collections as $data) {
    echo "Name: " .$data["name"] . "<br>";
    echo "Age:  " .$data["age"]  . "<br>";
}
