PG_FETCH_ARRAY(3)														 PG_FETCH_ARRAY(3)

pg_fetch_array - Fetch a row as an array

SYNOPSIS
array pg_fetch_array (resource $result, [int $row], [int $result_type = PGSQL_BOTH]) DESCRIPTION
pg_fetch_array(3) returns an array that corresponds to the fetched row (record). pg_fetch_array(3) is an extended version of pg_fetch_row(3). 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. Note This function sets NULL fields to the PHP NULL value. pg_fetch_array(3) is NOT significantly slower than using pg_fetch_row(3), and is significantly easier to use. PARAMETERS
o $result - PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others). o $row - Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or NULL, the next row is fetched. o $result_type - An optional parameter that controls how the returned array is indexed. $result_type is a constant and can take the following values: PGSQL_ASSOC, PGSQL_NUM and PGSQL_BOTH. Using PGSQL_NUM, pg_fetch_array(3) will return an array with numerical indices, using PGSQL_ASSOC it will return only associative indices while PGSQL_BOTH, the default, will return both numerical and associa- tive indices. 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(3) example <?php $conn = pg_pconnect("dbname=publisher"); if (!$conn) { echo "An error occurred. "; exit; } $result = pg_query($conn, "SELECT author, email FROM authors"); if (!$result) { echo "An error occurred. "; exit; } $arr = pg_fetch_array($result, 0, PGSQL_NUM); echo $arr[0] . " <- Row 1 Author "; echo $arr[1] . " <- Row 1 E-mail "; // 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 "; echo $arr["email"] . " <- Row 2 E-mail "; $arr = pg_fetch_array($result); echo $arr["author"] . " <- Row 3 Author "; echo $arr[1] . " <- Row 3 E-mail "; ?> SEE ALSO

fbsql_fetch_array - Fetch a result row as an associative array, a numeric array, or both

SYNOPSIS
array fbsql_fetch_array (resource $result, [int $result_type]) DESCRIPTION
fbsql_fetch_array(3) is a combination of fbsql_fetch_row(3) and fbsql_fetch_assoc(3). An important thing to note is that using fbsql_fetch_array(3) is NOT significantly slower than using fbsql_fetch_row(3), while it provides a significant added value. PARAMETERS
o $ result -A result identifier returned by fbsql_query(3) or fbsql_db_query(3). o $result_type - A constant and can take the following values: FBSQL_ASSOC, FBSQL_NUM, or FBSQL_BOTH. When using FBSQL_BOTH, in addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys. RETURN VALUES
Returns an array that corresponds to the fetched row, or FALSE if there are no more rows. If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you must the numeric index of the column or make an alias for the column. select t1.f1 as foo t2.f1 as bar from t1, t2 EXAMPLES
Example #1 fbsql_fetch_array(3) example <?php fbsql_connect($host, $user, $password); $result = fbsql_db_query("database", "select user_id, fullname from table"); while ($row = fbsql_fetch_array($result)) { echo "user_id: " . $row["user_id"] . "<br /> "; echo "user_id: " . $row[0] . "<br /> "; echo "fullname: " . $row["fullname"] . "<br /> "; echo "fullname: " . $row[1] . "<br /> "; } fbsql_free_result($result); ?> SEE ALSO
