filepro_retrieve — Fetches a record from a FilePro database.


string filepro_retrieve(row_offset, field_offset);
integer row_offset: Row offset
integer field_offset: Field offset


The specified FilePro record; FALSE on error


filepro_retrieve() fetches an individual record from a FilePro database. The function accepts two arguments: a row offset and a field offset.

By using this function with the filepro_fieldcount() and filepro_rowcount() functions, you can traverse the entire database.

If the specified offsets are outside the valid range or if another error occurs, the function returns FALSE and generates a warning-level error.


PHP Version: 3, 4+


Example 296. Traverse an entire database and display the results in a formatted text table

$fp_db = 'c:\fp\filepro\fpcust';

// Select the FilePro database
@ filepro ($fp_db)
    or die ("The '$fp_db' directory does not seem to contain a FilePro database map file.
        Please check the directory path, along with the directory and file permissions.");

$field_count = filepro_fieldcount ();
$row_count   = filepro_rowcount ();

// Print the top of the table
$line .= '| ';
for ($field_offset=0; $field_offset < $field_count; $field_offset++) {
    $width = filepro_fieldwidth ($field_offset);
    $name  = filepro_fieldname ($field_offset);

    $line .= sprintf ('<b>%-'.$width.'s</b> | ', $name);
    // Handle cases where the length of the field name is greater than the field length
    $field_width[$field_offset] = ($width < strlen ($name) ? strlen ($name) : $width);

// Make a separator for the table header
$separator = str_repeat ('-', strlen (strip_tags ($line)) - 1);

echo $separator, "\n", $line, "\n", $separator;

// Show all the records in the database
for ($row_offset=0; $row_offset < $row_count; $row_offset++) {
    print "\n| ";
    for ($field_offset=0; $field_offset < $field_count; $field_offset++) {
        printf ('%'.$field_width[$field_offset].'s | ', filepro_retrieve ($row_offset, $field_offset));

echo "\n", $separator;
