PHP provides various functions to access the MySQL database and to manipulate the data records inside the MySQL database CRUD (create, read, update and delete). You would require to call the PHP functions in the same way you call any other PHP function.

The PHP functions for use with MySQL have the following general format −

mysql_function(value,value,...);


The second part of the function name is specific to the function, usually a word that describes what the function does. The following are two of the functions, which we will use in our tutorial −

mysqli_connect($connect);
mysqli_query($connect,"SQL statement");


The following example shows a generic syntax of PHP to call any MySQL function.

<html>
<head>
<title>PHP with MySQL</title>
</head>

<body>
<?php
$retval = mysql_function(value, [value,...]);
if( !$retval ) {
die ( "Error: a related error message" );
}
// Otherwise MySQL or PHP Statements
?>
</body>
</html>
