dbase_numfields

Name

dbase_numfields — Finds the number of fields in a dbf file.

Synopsis

int dbase_numfields(dbf_identifier); int dbf_identifier: dbf identifier

Returns

Number of fields in a dbf file; FALSE on error

Description

dbase_numfields() returns the number of fields (columns) in a dbf file. Field numbers start at 0 and continue to one less than the number of fields in the dbf file. In other words, valid field numbers for a dbf file with four fields will range from 0to 3.

If the dbf_identifier argument doesn't refer to an open dbf file, FALSE is returned.

Example

Example 228. Find the number of fields in a dbf file

# path to dbm file
$db_file = '/tmp/sushi_eaten.dbf';

# open dbase file for read-only
$id = dbase_open ($db_file, '0')
    or die ("Could not open dbf file <i>$db_file</i>.");

echo "There are ", dbase_numfields ($id) , " fields in dbf file <i>$db_file</i>.";

dbase_close ($id);
