mysql_field_flags

Description

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().

Parameters

Return Values

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".

Examples

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; } $flags = mysql_field_flags($result, 0); echo $flags; print_r(explode(' ', $flags)); ?> The above example will output something similar to: not_null primary_key auto_increment Array ( [0] => not_null [1] => primary_key [2] => auto_increment )
