mysql_field_type
(PHP 3, PHP 4 )
mysql_field_type --
Get the type of the specified field in a result
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. The field type
will be one of "int", "real", "string", "blob", and others as
detailed in the MySQL
documentation.
Пример 1. MySQL field types <?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 would produce the following output:
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 |

For downward compatibility mysql_fieldtype()
can also be used. This is deprecated, however.
