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
";

	      ?>

mysql_fetch_assoc - Fetch a result row as an associative array

SYNOPSIS

       Warning

	      This  extension  is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_fetch_assoc(3)

		     o PDOStatement::fetch

       array mysql_fetch_assoc (resource  $result)

DESCRIPTION

	Returns an associative array that corresponds to the fetched row and moves the internal data pointer ahead. mysql_fetch_assoc(3) is equiv-
       alent to calling mysql_fetch_array(3) with MYSQL_ASSOC for the optional second parameter. It only returns an associative array.

	      o $
		result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).

	Returns an associative array of strings 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 either need to access the result with numeric indices by using mysql_fetch_row(3) or add alias names. See the example at the
       mysql_fetch_array(3) description about aliases.

       Example #1

	      An expanded mysql_fetch_assoc(3) example

	      <?php

	      $conn = mysql_connect("localhost", "mysql_user", "mysql_password");

	      if (!$conn) {
		  echo "Unable to connect to DB: " . mysql_error();
		  exit;
	      }

	      if (!mysql_select_db("mydbname")) {
		  echo "Unable to select mydbname: " . mysql_error();
		  exit;
	      }

	      $sql = "SELECT id as userid, fullname, userstatus
		      FROM   sometable
		      WHERE  userstatus = 1";

	      $result = mysql_query($sql);

	      if (!$result) {
		  echo "Could not successfully run query ($sql) from DB: " . mysql_error();
		  exit;
	      }

	      if (mysql_num_rows($result) == 0) {
		  echo "No rows found, nothing to print so am exiting";
		  exit;
	      }

	      // While a row of data exists, put that row in $row as an associative array
	      // Note: If you're expecting just one row, no need to use a loop
	      // Note: If you put extract($row); inside the following loop, you'll
	      //       then create $userid, $fullname, and $userstatus
	      while ($row = mysql_fetch_assoc($result)) {
		  echo $row["userid"];
		  echo $row["fullname"];
		  echo $row["userstatus"];
	      }

	      mysql_free_result($result);

	      ?>

       Note

	      Performance

	       An  important  thing to note is that using mysql_fetch_assoc(3) is not significantly slower than using mysql_fetch_row(3), while it
	      provides a significant added value.

       Note

	      Field names returned by this function are case-sensitive.

       Note

	      This function sets NULL fields to the PHP NULL value.
