mysqli_result::fetch_all - Fetches all result rows as an associative array, a numeric array, or both

       Object oriented style

SYNOPSIS

       mixed mysqli_result::fetch_all ([int  $resulttype = MYSQLI_NUM])

DESCRIPTION

       Procedural style
       mixed mysqli_fetch_all (mysqli_result  $result, [int  $resulttype = MYSQLI_NUM])

       mysqli_fetch_all(3) fetches all result rows and returns the result set as an associative array, a numeric array, or both.

PARAMETERS

	      o $
		result	 -Procedural   style   only:   A   result   set   identifier   returned   by  mysqli_query(3),	mysqli_store_result(3)	or
		mysqli_use_result(3).

	      o $resulttype
		- This optional parameter is a constant indicating what type of array should be produced from the current row data.  The  possible
		values for this parameter are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH.

RETURN VALUES

	Returns an array of associative or numeric arrays holding result rows.

MYSQL NATIVE DRIVER ONLY

	Available only with mysqlnd.

	As  mysqli_fetch_all(3)  returns all the rows as an array in a single step, it may consume more memory than some similar functions such as
       mysqli_fetch_array(3), which only returns one row at a time from the result set. Further, if you need to iterate over the result  set,  you
       will need a looping construct that will further impact performance. For these reasons mysqli_fetch_all(3) should only be used in those sit-
       uations where the fetched result set will be sent to another layer for processing.

mysqli_result::fetch_assoc - Fetch a result row as an associative array

       Object oriented style

SYNOPSIS

       array mysqli_result::fetch_assoc (void  )

DESCRIPTION

       Procedural style
       array mysqli_fetch_assoc (mysqli_result	$result)

	Returns an associative array that corresponds to the fetched row or NULL if there are no more rows.

       Note

	      Field names returned by this function are case-sensitive.

       Note

	      This function sets NULL fields to the PHP NULL value.

PARAMETERS

	      o $
		result	 -Procedural   style   only:   A   result   set   identifier   returned   by  mysqli_query(3),	mysqli_store_result(3)	or
		mysqli_use_result(3).

RETURN VALUES

	Returns an associative array of strings representing the fetched row in the result set, where each key in the array represents the name of
       one of the result set's columns or NULL if there are no more rows in resultset.

	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 mysqli_fetch_row(3) or add alias names.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if ($mysqli->connect_errno) {
		  printf("Connect failed: %s
", $mysqli->connect_error);
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

	      if ($result = $mysqli->query($query)) {

		  /* fetch associative array */
		  while ($row = $result->fetch_assoc()) {
		      printf ("%s (%s)
", $row["Name"], $row["CountryCode"]);
		  }

		  /* free result set */
		  $result->free();
	      }

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

	      if ($result = mysqli_query($link, $query)) {

		  /* fetch associative array */
		  while ($row = mysqli_fetch_assoc($result)) {
		      printf ("%s (%s)
", $row["Name"], $row["CountryCode"]);
		  }

		  /* free result set */
		  mysqli_free_result($result);
	      }

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      Pueblo (USA)
	      Arvada (USA)
	      Cape Coral (USA)
	      Green Bay (USA)
	      Santa Clara (USA)

       Example #3

	      A mysqli_result example comparing iterator usage

	      <?php
	      $c = mysqli_connect('127.0.0.1','user', 'pass');

	      // Using iterators (support was added with PHP 5.4)
	      foreach ( $c->query('SELECT user,host FROM mysql.user') as $row ) {
		  printf("'%s'@'%s'
", $row['user'], $row['host']);
	      }

	      echo "
==================
";

	      // Not using iterators
	      $result = $c->query('SELECT user,host FROM mysql.user');
	      while ($row = $result->fetch_assoc()) {
		  printf("'%s'@'%s'
", $row['user'], $row['host']);
	      }

	      ?>

	      The above example will output something similar to:

	      ==================
