How do I rewrite the code in order to avoid the repetition of the block case 3:{code block A; break;}?

switch(i) { case 1: {code block A; break;} case 2: {code block b; break;} case 3: {code block A; break;} default: {code block default; break;}}How can I have combined code for case 1 and case 3?



Trending sort Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.

It falls back to sorting by highest score if no posts are trending.

Switch to Trending sort
Highest score (default) Trending (recent votes count more) Date modified (newest first) Date created (oldest first)
This format is shown in the PHP docs:

switch (i) { case 1: case 3: code block A; break; case 2: code block B; break; default: code block default; break;}With the release of PHP8 and the new match function, it is often a better solution to use match instead of switch.

For the example above, the equivalent with match would be :

$matchResult = match($i) { 1, 3 => // code block A 2 => // code block B default => // code block default}The match statement is shorter, doesn”t require breaks and returns a value so you don”t have to assign a value multiple times.

Moreover, match will act like it was doing a === instead of a ==. This will probably be subject to discussion but it is what it is.

Something like

$i = 10; switch($i){ case $i == 1 || $i > 3: echo “working”; break; case 2: echo “i = 2”; break; default: echo “i = $i”; break; }
