pg_result_seek - Set internal row offset in result resource

SYNOPSIS

       bool pg_result_seek (resource  $result, int  $offset)

DESCRIPTION

       pg_result_seek(3) sets the internal row offset in a result resource.

PARAMETERS

	      o $result
		- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).

	      o $offset
		- Row to move the internal offset to in the $result resource. Rows are numbered starting from zero.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      pg_result_seek(3) example

	      <?php

	      // Connect to the database
	      $conn = pg_pconnect("dbname=publisher");

	      // Execute a query
	      $result = pg_query($conn, "SELECT author, email FROM authors");

	      // Seek to the 3rd row (assuming there are 3 rows)
	      pg_result_seek($result, 2);

	      // Fetch the 3rd row
	      $row = pg_fetch_row($result);

	      ?>

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
";

	      ?>
