mysql_field_typeSynopsis
Descriptionmysql_field_type() returns the type of the specified field in a query. The field_offset argument specifies the desired field. Field offsets start at 0. The types returned by this function are similar but not identical to MySQL's column types. If the column value is generated by an expression, the type of the result determines the type of the column. For example, suppose this is the query: SELECT count(user); The type would be int. The following table lists the types.
ExampleExample 815. Find the field types for the fields in a query <?php // Included code that connects to a MySQL server and sets a default database // See the MySQL Functions chapter introduction for the source code for the file include ('mysql_connect.inc.php'); // A SELECT query using a column name and a few functions $query = "SELECT login, UNIX_TIMESTAMP(), NOW() FROM user"; // Run the query $mysql_result = @ mysql_query ($query) or die ("Query '$query' failed with error message: \"" . mysql_error () . '"'); // Grab information on every other field in the result set // Display the object containing field information for ($offset = 0; $offset < mysql_num_fields ($mysql_result); ++$offset) { // Find the name of the current field $field_name = mysql_field_name ($mysql_result, $offset); // Find the type of the current field $field_type = mysql_field_type ($mysql_result, $offset); echo "Field '$field_name' is of type '$field_type'.<br />"; } ?>
