mysql_field_type

(PHP 3, PHP 4)

mysql_field_type - получает тип специфицированного поля результата.

Описание

string mysql_field_type (resource result, int field_offset)

mysql_field_type() аналогична mysql_field_name(). Аргументы идентичны, но возвращается тип поля. Это может быть "int", "real", "string", "blob" и другие типы, как уточнено в MySQL-документации.
Пример 1. Типы полей MySQL
<?php
    mysql_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();
?>

Пример даст на выходе:

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

Для обеспечения обратной совместимости можно также использовать mysql_fieldtype(), но это не рекомендуется.
