You're probably running into an issue where the browser isn't outputting anything until a certain amount of data has been downloaded. The threshold in Chrome is 1KB (I think). So an example that could work in your case, could look like this: "; // Added buffer sleep(1); // visual aid ob_flush(); flush(); $counter++; } echo $buffer."All done!"; // more buffer ob_end_flush(); You're code isn't really doing anything wrong, it's just your client that impacts your results.

November 12, 2021Is it bad practice to use foreach instead of while?
Always use FOREACH when iterating over a whole array, or at least from the top of an array to a BREAK condition. This way you will never be bitten by an "off by one" error. Always use FOR when you know (or can easily determine) exactly how many times you need to execute the code in the loop. This is also useful for iterating parts of an array where you aren't always going to be starting from the head. Use a DO-WHILE when the number of times to have to execute the loop is indeterminate, but you know the code must execute at least once. Use a WHILE loop when the looping condition could be false as you enter the loop. In other words, there could be conditions where you never execute the loop. More on reddit.com

June 17, 2014Using variable inside WHILE looop
As long as $row is not falsey it will loop. Each loop iteration it checks what $row is and stops if there are no additional rows. There are some standards that avoid this syntax (declaring a variable in an if or loop) but it works. It is often a mistake or seen as a mistake as you usually use == in the same context, but the alternative to this would uses more lines of code. It's the same as: while ( true ) { $row = ...; if ( ! $row ) { break; } } More on reddit.com

mysql_fetch_array() only retrieves a single row from the database. You need to call it inside your while loop to retrieve all rows. The $looping increment is unnecessary here, since mysql_fetch_array() returns false when no more rows are available.
Copywhile ($row = mysql_fetch_array($result))
{
echo $row["Name"].", Room ".$row["Room"].", Tel ".$row["Telephone"] ;
}
