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

Warning

This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

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

### 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 » 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
