If / Equality / String Fail

[chaosxkitten]

I'm adding html tags with an "if" statement.

 

$fw = "word"
if ($fw == "a"){
  echo "something";
}elseif ($fw == "b"){
  echo "something else";
}else{
  echo "this";
}

 

So why would everything skip right to the "else" and echo that, even if $fw equals "a" or "b"....

It shouldn't. I just pasted your code locally and ran it, and it works as intended. Post the actual code you're having problems with.

Here's all of it, maybe the error is somewhere else. I added a check that would print the $fw variable, and everything prints as it should, but my webpage is here and not working well http://easlnx01.eas.muohio.edu/~meadecm/project02.php

 

 <?php

//Returns the first word of a paragraph
function getFirstWord($p,$x) {
    $str = $p[$x];
    $word = explode(" ",$str);
    return $word[0];
}

// Opens the constitution text file, writes to a variable, explodes.
$data = file_get_contents('constitution.txt');
$paragraphs = explode("&",$data);


// Formats the Preamble.
echo "<p><em>$paragraphs[0]</em></p>";

// Runs through some if statements to determine the tags to use on remander.

$n = 1;

do {
    $fw = getFirstWord($paragraphs,$n); 
    if ($fw == 'Article'){
echo "<h2>$paragraphs[$n]</h2>";
    }
    elseif ($fw  == 'Section'){
echo "<h3>$paragraphs[$n]</h3>";
    }
    elseif ($fw == 'Amendment'){
echo "<h3>$paragraphs[$n]</h3>";
    }
    else{
echo "<p>$paragraphs[$n]</p>";
    }
    $n += 1;
    echo "\$fw=$fw\n";
}  while (count($paragraphs) >= $n) 

?>

Without having the text file, All I can really do is make an educated guess, but it may be that there's whitespace causing the comparison to evaluate to false. Try trimming the values before comparing them.

 

if ( trim($fw) == 'Article' ) { // ETC.
