This section describes all 8 data types supported in PHP with a tutorial example showing how to use them: boolean, integer, float, string, array, object, resource, null. PHP supports 8 data types: boolean: It has only two literal values: ‘true’ and ‘false’.
31,"Feb"=>28,"Mar"=>31); // array data type print "\n Array data type - Days in each month: " .$monthDays['Jan'].", ".$monthDays['Feb'].", ".$monthDays['Mar'] .".

Null data type - Null means nothing:?>How to: Specify PHP Data Types
The following steps summarize how to specify PHP data types when retrieving data from the server using the SQLSRV driver: Set up and execute a Transact- SQL query with sqlsrv_query or the combination of sqlsrv_prepare / sqlsrv_execute. Make a row of data available for reading with sqlsrv_fetch. Retrieve field data from a returned row using
"AdventureWorks"); $conn = sqlsrv_connect( $serverName, $connectionInfo); if( $conn === false ) < echo "Could not connect.\n"; die( print_r( sqlsrv_errors(), true)); >/* Set up the Transact-SQL query. */ $tsql = "SELECT ReviewerName, ReviewDate, Rating, Comments FROM Production.ProductReview WHERE ProductID = ? ORDER BY ReviewDate DESC"; /* Set the parameter value. */ $productID = 709; $params = array( $productID); /* Execute the query. */ $stmt = sqlsrv_query($conn, $tsql, $params); if( $stmt === false ) < echo "Error in statement execution.\n"; die( print_r( sqlsrv_errors(), true)); >/* Retrieve and display the data. The first and third fields are retrieved according to their default types, strings. The second field is retrieved as a string with 8-bit character encoding. The fourth field is retrieved as a stream with 8-bit character encoding.*/ while ( sqlsrv_fetch( $stmt)) < echo "Name: ".sqlsrv_get_field( $stmt, 0 )."\n"; echo "Date: ".sqlsrv_get_field( $stmt, 1, SQLSRV_PHPTYPE_STRING( SQLSRV_ENC_CHAR))."\n"; echo "Rating: ".sqlsrv_get_field( $stmt, 2 )."\n"; echo "Comments: "; $comments = sqlsrv_get_field( $stmt, 3, SQLSRV_PHPTYPE_STREAM(SQLSRV_ENC_CHAR)); fpassthru( $comments); echo "\n"; >/* Free statement and connection resources. */ sqlsrv_free_stmt( $stmt); sqlsrv_close( $conn); ?>Which databases are supported by PHP?
On Windows machines, you can simply use the included ODBC support and the correct ODBC driver.
On Unix machines, you can use the Sybase-CT driver to access Microsoft SQL Servers because they are (at least mostly) protocol-compatible. Sybase has made a » free version of the necessary libraries for Linux systems. For other Unix operating systems, you need to contact Sybase for the correct libraries. Also see the answer to the next question.

PHP MySQL Database
With PHP, you can connect to and manipulate databases.
MySQL is the most popular database system used with PHP.
What is MySQL?
- MySQL is a database system used on the web
- MySQL is a database system that runs on a server
- MySQL is ideal for both small and large applications
- MySQL is very fast, reliable, and easy to use
- MySQL uses standard SQL
- MySQL compiles on a number of platforms
- MySQL is free to download and use
- MySQL is developed, distributed, and supported by Oracle Corporation
- MySQL is named after co-founder Monty Widenius’s daughter: My
The data in a MySQL database are stored in tables. A table is a collection of related data, and it consists of columns and rows.
Databases are useful for storing information categorically. A company may have a database with the following tables:
PHP + MySQL Database System
- PHP combined with MySQL are cross-platform (you can develop in Windows and serve on a Unix platform)
Database Queries
A query is a question or a request.
We can query a database for specific information and have a recordset returned.
Look at the following query (using standard SQL):
The query above selects all the data in the «LastName» column from the «Employees» table.
