is being evaluated. This result comes from a call to
mysql_query() .

field_offset starts at 0 . If
field_offset does not exist, an error of level
E_WARNING is also issued.

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
