mysql_field_flags

(PHP 4, PHP 5, PECL mysql:1.0)

mysql_field_flags — Get the flags associated with the specified field in a result

Descrierea

string mysql_field_flags ( resource $result , int $field_offset )

mysql_field_flags() returns the field flags of the specified field. The flags are reported as a single word per flag separated by a single space, so that you can split the returned value using explode().

Parametri

result

Rezultatul de tip resource, care este evaluat. Acest rezultat provine de la apelul funcţiei mysql_query().

field_offset

Deplasamentul numeric al câmpului. field_offset începe de la 0. Dacă field_offset nu există, se generează de asemenea o eroare de nivel E_WARNING.

Valorile întroarse

Returns a string of flags associated with the result, or FALSE on failure.

The following flags are reported, if your version of MySQL is current enough to support them: "not_null", "primary_key", "unique_key", "multiple_key", "blob", "unsigned", "zerofill", "binary", "enum", "auto_increment" and "timestamp".

Exemple

Example#1 A mysql_field_flags() example

<?php
$result 
mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!
$result) {
    echo 
'Could not run query: ' mysql_error();
    exit;
}
$flags mysql_field_flags($result0);

echo 
$flags;
print_r(explode(' '$flags));
?>

Exemplul de mai sus va afiÅŸa ceva similar cu:

not_null primary_key auto_increment
Array
(
    [0] => not_null
    [1] => primary_key
    [2] => auto_increment
)

Note
