Body
<p>During an exercise I combined a while loop with an if/else clause, and thus decided to convert the if/else to use switch statement instead, just to challenge my mind.</p> <p>The program is simple: there are two players that have to win 3 consecutive matches to stop the game. The players values are sorted randomly between 0 and 1, and there is a cap to the pair matches, just in the case randomness would ever win the race :)</p> <p>I would like to understand which one is the best solution, and why, because to me it seems just that the switch version needs few lines of codes more!</p> <pre><code><?php $playerA=0; $playerB=0; $winA=0; $winB=0; $pair=0; while ($winA<=2 && $winB<=2 && $pair<=15) { $playerA = rand(0,1); $playerB = rand(0,1); if ($playerA > $playerB) { $winA ++; $winB=0; echo "<div>Player A Wins.</div>"; } elseif ($playerA < $playerB) { $winB ++; $winA=0; echo "<div>Player B Wins.</div>"; } elseif ($playerA == $playerB) { $pair ++; $winA=0; $winB=0; echo "<div>Pair, play again!</div>"; } } echo "<div>There is a total of {$pair} pair matches</div>"; ?> </code></pre> <p>And now the switch one...</p> <pre><code><?php $playerA=0; $playerB=0; $winA=0; $winB=0; $pair=0; while ($winA<=2 && $winB<=2 && $pair<=15) { $playerA = rand(0,1); $playerB = rand(0,1); switch ($playerA && $playerB): //This is an error: it should have been switch(true) case ($playerA > $playerB): $winA++; $winB=0; echo "<div>Player A Wins.</div>"; break; case ($playerA < $playerB): $winB++; $winA=0; echo "<div>Player B Wins.</div>"; break; case ($playerA == $playerB): $pair++; $winA=0; $winB=0; echo "<div>Pair, Play again!</div>"; break; endswitch; } echo "<div>There is a total of {$pair} pair matches</div>"; ?> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
