mysql_field_type

Get the type of the specified field in a result (PHP 3, PHP 4 )
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 602. 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.
