mysql_field_type

(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. The field type will be one of "int", "real", "string", "blob", and others as detailed in the MySQL 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);
$table = mysql_field_table($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.
