Description

mysql_field_type ( resource $result , int $field_offset ) : string

mysql_field_type() is similar to the mysql_field_name() function. The arguments are identical, but the field type is returned instead.


Parameters

result
The result resource that is being evaluated. This result comes from a call to mysql_query().
field_offset
The numerical field offset. The field_offset starts at 0. If field_offset does not exist, an error of level E_WARNING is also issued.


Return Values

The returned field type will be one of "int", "real", "string", "blob", and others as detailed in the [http://dev.mysql.com/doc/ » MySQL documentation].


Examples

Example #1 mysql_field_type() example

<?phpmysql_connect("localhost", "mysql_username", "mysql_password");mysql_select_db("mysql");$result = mysql_query("SELECT * FROM func");$fields = mysql_num_fields($result);$rows   = mysql_num_rows($result);$table  = mysql_field_table($result, 0);echo "Your '" . $table . "' table has " . $fields . " fields and " . $rows . " record(s)\n";echo "The table has the following fields:\n";for ($i=0; $i < $fields; $i++) {    $type  = mysql_field_type($result, $i);    $name  = mysql_field_name($result, $i);    $len   = mysql_field_len($result, $i);    $flags = mysql_field_flags($result, $i);    echo $type . " " . $name . " " . $len . " " . $flags . "\n";}mysql_free_result($result);mysql_close();?>

The above example will output something similar to:


Your 'func' table has 4 fields and 1 record(s)
The table has the following fields:
string name 64 not_null primary_key binary
int ret 1 not_null
string dl 128 not_null
string type 9 not_null enum
