(PHP 3, PHP 4, PHP 5)
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.
Parameters
resultThe result resource that
is being evaluated. This result comes from a call to
mysql_query().
field_offsetThe 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
<?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 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 |
