mysql_field_type() is similar to the mysql_field_name() function. The argumens are identical, but the field type is returned instead.

stars at

. If

does not exist, an error of level

will be one of
"int"
,
"real"
,
"string"
,
"blob"
, and others as
detailed in the

documentation
.
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

$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

$len
=
mysql_field_len
(
$result

echo
$type
