pg_fetch_row

Name

pg_fetch_row — Fetches a row of data.

Synopsis

object pg_fetch_row(result, row); int result: Result identifier int row: Row

Returns

Current record or FALSE

Description

Reads the current row in the PostgreSQL result set and returns an array with each element containing the value of the corresponding field and each key containing the field offset - not the field name, as with pg_fetch_array() . The field offset numbering starts at 0. If looping through the result set is required, the total number of rows returned from the result set can be determined from pg_numrows() . The result type was introduced in PHP4 and is a constant with one of three values: PGSQL_ASSOC, PGSQL_NUM, or PGSQL_BOTH.

Version

Existing since version 3.0.1

Example

Example 1033. Display data from an array

$db = pg_connect("host=dbserver dbname=db user=dbuser password=dbpasswd");
$sql = "SELECT * FROM employees";
if (!$result = @pg_exec($sql)) {
    // error
    echo pg_errormessage($db);
} else {
    // display results
    for ($i=0;$i<pg_numrows($result);$i++) {
        $row = pg_fetch_row($result,$i);
        printf("%s %s\n", $row[1], $row[2]);
    }
}
