looping through the alphabet

webosb · 09-23-2010, 03:25 PM

I'm trying to mess around with arrays right now relating to letters in the alphabet. Is there anyway to code this better:

PHP Code:


			
<?php

header("Content-type: text/plain");

        $arr = array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z");



        for ($t=0; $t<26; $t++){

            for ($t1=0; $t1<26; $t1++){

                if(($arr[$t].$arr[$t1]) == "MA"){

                    for ($t2=0; $t2<26; $t2++){

                        echo $arr[$t].$arr[$t1].$arr[$t2]. "\n";

                    }

                }else{

                        echo $arr[$t].$arr[$t1]. "\n";

                }



            }

        }

I'm not really sure "better" would be the correct term to use, but there are a few things I'd do differently.

First would be to use the range() (docs) function to generate the array of letters: range('A', 'Z') I'd also use foreach since you simple want to loop over all of the values present in the array.

Is there anything you're unsure about, when using or looping through arrays?

OK... I did take out a function I wrote which counted results per number... Inside the each loop.. there is a count function that would count the amount of values and if it exceeded 200, it would go two letters deep and if needed then three letters deep. Maybe I'm overthinking this... but i been trying to figure this out for a couple hours now. I was able to do it manually like in the code sample above. But I was thinking how it could be possible to make it automatically detect any character result count and automatically go an extra level deep if needed. is this possible to do this automatically?

PHP Code:


			
<?php

header("Content-type: text/plain");

$arr = array("A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z");



        for ($t=0; $t<26; $t++){

        $oneLetter = countData($blah);

        if($oneLetter >= 200){ //if the results for oneLetter is 200 or more then go one extra letter

            for ($t1=0; $t1<26; $t1++){

                $twoLetter = countData($blah);

                if($twoLetter >= 200){ //if the results for twoLetter is 200 or more then go one extra letter

                    for ($t2=0; $t2<26; $t2++){

                        echo $arr[$t].$arr[$t1].$arr[$t2]. "\n";

                    }

                }else{

                        echo $arr[$t].$arr[$t1]. "\n";

                }



            }

        }
