pg_fetch_array

Description

pg_fetch_array() returns an array that corresponds to the fetched row (record).

pg_fetch_array() is an extended version of pg_fetch_row(). In addition to storing the data in the numeric indices (field number) to the result array, it can also store the data using associative indices (field name). It stores both indicies by default.

pg_fetch_array() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.

Parameters

Return Values

An array indexed numerically (beginning with 0) or associatively (indexed by field name), or both. Each value in the array is represented as a string. Database NULL values are returned as NULL.

FALSE is returned if row exceeds the number of rows in the set, there are no more rows, or on any other error.

Examples

Example 1. pg_fetch_array() example <?php $conn = pg_pconnect("dbname=publisher"); if (!$conn) {   echo "An error occured.\n";   exit; } $result = pg_query($conn, "SELECT author, email FROM authors"); if (!$result) {   echo "An error occured.\n";   exit; } $arr = pg_fetch_array($result, 0, PGSQL_NUM); echo $arr[0] . " <- Row 1 Author\n"; echo $arr[1] . " <- Row 1 E-mail\n"; // As of PHP 4.1.0, the row parameter is optional; NULL can be passed instead, // to pass a result_type.  Successive calls to pg_fetch_array will return the // next row. $arr = pg_fetch_array($result, NULL, PGSQL_ASSOC); echo $arr["author"] . " <- Row 2 Author\n"; echo $arr["email"] . " <- Row 2 E-mail\n"; $arr = pg_fetch_array($result); echo $arr["author"] . " <- Row 3 Author\n"; echo $arr[1] . " <- Row 3 E-mail\n"; ?>
