the following code is totally wrong just explain what i want

$variableA = "hello"
if (variableA == a) { echo "hello"; }
elseif (variableA == b) { echo "matched"; }
elseif (variableA == c) { echo "matched"; }
elseif (variableA == d) { echo "matched"; }
elseif (variableA == e) { echo "matched"; }
elseif (variableA == f) { echo "matched"; }
elseif (variableA == g) { echo "matched"; }
elseif (variableA == h) { echo "matched"; }
elseif (variableA == i) { echo "matched"; }
// so on untill z then it woulc be like
elseif (variableA == aa) { echo "matched"; }
elseif (variableA == bb) { echo "matched"; }
//so on an on an on

<?php
$answerArray = array("a" => "A!", "b" => "B!", "c" => "C!", "d" => "D!");
$variableA = "c";

foreach ($answerArray as $selection => $answer) {
      if ($selection == $variableA) {
            print $answer;
            break;
      }
}
?>

 

Something like  that would work.

<?php
$answerArray = array("a" => "A!", "b" => "B!", "c" => "C!", "d" => "D!");
$variableA = "c";

foreach ($answerArray as $selection => $answer) {
      if ($selection == $variableA) {
            print $answer;
            break;
      }
}
?>

 

Something like  that would work.

and with this it just gets the first letter what is the ! for

"a" => "A!"

The ! is nothing, that is the value you want to print out.

 

It could of been this:

 

<?php
$answerArray = array("a" => "You selected A!", "b" => "You selected B!", "c" => "You selected C!", "d" => "You selected D!");
$variableA = "c";

foreach ($answerArray as $selection => $answer) {
      if ($selection == $variableA) {
            print $answer; // prints You selected C!
            break; // remove this if you want the loop to go through every element of the array.
      }
}
?>

I think you are missing the point of the array.

 

www.php.net/array

 

The array seen above is considered an associative array. The first part IE: "a" =>  is the KEY of the array, meaning you can acesses the second part or the value "You selected A!" by calling $array["a"]  and that will print out "You selected A!"

 

So if $variableA = "a"; it will print out "You selected A!" using the loop I created above.

 

If $variableA = "c"; it will print out "You selected C!";

 

It works the same as the following:

<?php
$answerArray = array("a" => "You selected A!", "b" => "You selected B!", "c" => "You selected C!", "d" => "You selected D!");
$variableA = "c";
print $answerArray[$variableA]; // Prints "You selected C!" since the index of "c" value is "You Selected C!";
?>

 

I would highly suggest you read up on arrays and how they are used.

Maybe you are looking for something similiar to this ???

 

<?php
$mainArticle = 'Computer programming is one of the best for certain php languages that are not of this world! that';

$articles[0] = 'This is a topic that is totally not related to the first article at all!';
$articles[1] = 'Programming in PHP has done miraculous wonders to this time and many other exciting events!';
$articles[2] = 'Programming This is a topic that is totally not related to the first article at all';
$articles[3] = 'Programming in Computer language PHP has done This is a topic that is totally not related to the first article at all';
$articles[4] = 'Certainly this is not a computer topic This is a topic that is totally not related to the first article at all or is it world of languages';
$articles[5] = 'Jack and jill went up the hill to fetch a pail of water, jack fell down and broke his crown and jill came tumbling after!';

$related = relatedTest($mainArticle, $articles);
print "The following articles are related to : " . $mainArticle . " (ordered by most revlevant)<br /><br />";
foreach ($related as $key => $matches) {
print "Article: " . $articles[$key] . "<br />";
}

print "<br /><br /><br />These were all the articles used.<br /><br />";

foreach ($articles as $article) {
print $article . "<br />";
}

function relatedTest($mainArticle, $articles) {
$mainArticle = stripCommons($mainArticle);
$words = explode(" ", $mainArticle);

foreach ($articles as $key => $article) {
	$artWords[$key] = explode(" ", stripCommons($article));

	$matches = compareWords($words, $artWords[$key]);

	if ($matches > 0) {
		$match[$key] = $matches;
	}else {
		unset($artWords[$key]);
	}
}
arsort($match);
return $match;
}

function compareWords($words, $compwords) {
$match = 0;
if (is_array($words)) {
	foreach ($words as $word) {
		foreach ($compwords as $compword) {
			if (strtolower($compword) == strtolower($word)) {
				$match++;
			}
		}
	}
}

return $match;
}

function stripCommons($article) {
$article = ereg_replace("'|\.|\?|!|,|\"|&|:|-|\[|\]|\(|\)|\+|=|~|\||\*|\^|%|\$|@|#|<|>|`|;|_|\{|\}", "", $article);
$article = " " . $article . " ";
$commonWords = array("if", "u", "so", "it", "its", "is", "of", 
					"or", "by", "on", "but", "a", "was", "for", "it", 
						"this", "was", "to", "are", "can", "you", "your", 
						"any", "or", "the", "with", "this", "not", "at", "and", "that");
$commonWords = strlenSort($commonWords);	

foreach ($commonWords as $word) {
	if (eregi(" ".$word." ", $article)) {
		$article = str_replace(" ".$word." ", " ", $article);
	}
}

return trim($article);
}

function strlenSort($array) {
// sort array by string length
foreach ($array as $key => $size) {
	$newArray[$key] = strlen($size);
}
arsort($newArray, SORT_NUMERIC);

$i=0;
foreach ($newArray as $key => $size) {
	$returnArr[$i++] = $array[$key];
}

return $returnArr;
}
?>

 

 

Which when ran would produce:

 

he following articles are related to : Computer programming is one of the best for certain php languages that are not of this world! that (ordered by most revlevant)

Article: Certainly this is not a computer topic This is a topic that is totally not related to the first article at all or is it world of languages
Article: Programming in Computer language PHP has done This is a topic that is totally not related to the first article at all
Article: Programming in PHP has done miracuouls wonders to this time and many other exciting events!
Article: Programming This is a topic that is totally not related to the first article at all



These were all the articles used.

This is a topic that is totally not related to the first article at all!
