Question

Okay, so I realize that when do:

//connection code;

//query code;

//$result= mysqli_query();

$row= mysqli_fetch_array($result);

you create an associative array where the column names from your table are the keys for the data in the respective row.

Then you can use:

while ($row= mysqli_fetch_array($result))
{
//code to echo out table data.
}

My question is how does the while loop go to the next row after each iteration? I thought that was what foreach loops were for?

Answer 1

From http://www.php.net/manual/en/function.mysql-fetch-array.php

array mysql_fetch_array ( resource $result [, int $result_type = MYSQL_BOTH ] )
Returns an array that corresponds to the fetched row and moves the internal data pointer ahead.
