MYSQL_FETCH_ARRAY(3)							 1						      MYSQL_FETCH_ARRAY(3)

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

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_array(3)

		     o PDOStatement::fetch

       array mysql_fetch_array (resource  $result, [int  $result_type = MYSQL_BOTH])

DESCRIPTION

	Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.

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

	      o $result_type
		- The type of array that is to be fetched. It's a constant  and  can  take  the  following  values:  MYSQL_ASSOC,  MYSQL_NUM,  and
		MYSQL_BOTH.

	Returns an array of strings that corresponds to the fetched row, or FALSE if there are no more rows. The type of returned array depends on
       how $result_type is defined. By using MYSQL_BOTH  (default),  you'll  get  an  array  with  both  associative  and  number  indices.  Using
       MYSQL_ASSOC,  you  only	get  associative  indices  (as	mysql_fetch_assoc(3)  works),  using  MYSQL_NUM,  you  only get number indices (as
       mysql_fetch_row(3) works).

	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 use the numeric index of the column or make an alias for the column. For aliased columns, you cannot access the con-
       tents with the original column name.

       Example #1

	      Query with aliased duplicate field names

	      SELECT table1.field AS foo, table2.field AS bar FROM table1, table2

       Example #2

	      mysql_fetch_array(3) with MYSQL_NUM

	      <?php
	      mysql_connect("localhost", "mysql_user", "mysql_password") or
		  die("Could not connect: " . mysql_error());
	      mysql_select_db("mydb");

	      $result = mysql_query("SELECT id, name FROM mytable");

	      while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
		  printf("ID: %s  Name: %s", $row[0], $row[1]);
	      }

	      mysql_free_result($result);
	      ?>

       Example #3

	      mysql_fetch_array(3) with MYSQL_ASSOC

	      <?php
	      mysql_connect("localhost", "mysql_user", "mysql_password") or
		  die("Could not connect: " . mysql_error());
	      mysql_select_db("mydb");

	      $result = mysql_query("SELECT id, name FROM mytable");

	      while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
		  printf("ID: %s  Name: %s", $row["id"], $row["name"]);
	      }

	      mysql_free_result($result);
	      ?>

       Example #4

	      mysql_fetch_array(3) with MYSQL_BOTH

	      <?php
	      mysql_connect("localhost", "mysql_user", "mysql_password") or
		  die("Could not connect: " . mysql_error());
	      mysql_select_db("mydb");

	      $result = mysql_query("SELECT id, name FROM mytable");

	      while ($row = mysql_fetch_array($result, MYSQL_BOTH)) {
		  printf ("ID: %s  Name: %s", $row[0], $row["name"]);
	      }

	      mysql_free_result($result);
	      ?>

       Note

	      Performance

	       An important thing to note is that using mysql_fetch_array(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.
