# mysql_field_type

(PHP 4, PHP 5)

mysql_field_type — Get the type of the specified field in a result

Warning

This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

- mysqli_fetch_field_direct() [type]
- PDOStatement::getColumnMeta() [driver:decl_type] or [pdo_type]

### Description

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

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 » MySQL documentation.

### Examples

Example #1 mysql_field_type() example

`<?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();
?>`

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
