PHP str_replace奇怪的结果

Question

i have these codes:

$alphabet = 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");

$first = array("Captain","Dirty","Squidlips","Bowman","Buccaneer","Two Toes","Sharkbait","Old","Peg Leg","Fluffbucket","Scallywag","Bucko","Dead man","Matey","Jolly","Stinky","Bloody","Miss","Mad","Red","Lady","Bretheren","Rapscallion","Landlubber","Wench","Freebooter");

ImageTTFText($image, 45, 0, 0, $y-intval("30"), imageColorAllocate($image,255,255,255), "pirate-font.ttf", str_replace($alphabet,$first,"bad")); 

Please help me fix this weird problem... i think there is something wrong they i coded it, but i don't know which is which...

With the code above...

supposedly, the output must be Dirty Captain Bowman but it's odd that it outputs the wrong result...

The left to right functionality of str_replace causes this, unfortunately. So here is an alternative.

Here is an example of the code below: Example.

$alphabet = 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");

$first = array("Captain","Dirty","Squidlips","Bowman","Buccaneer","Two Toes","Sharkbait","Old","Peg Leg","Fluffbucket","Scallywag","Bucko","Dead man","Matey","Jolly","Stinky","Bloody","Miss","Mad","Red","Lady","Bretheren","Rapscallion","Landlubber","Wench","Freebooter");

// split bad into an array, each letter being its own value.
$input = str_split('bad');

// Alphabet become the keys, $first are the values
$c = array_combine($alphabet, $first);

$output = '';
foreach ($input as $letter)
{
    $output .= $c[$letter] . ' ';
}

$final_word = trim($output);

ImageTTFText($image, 45, 0, 0, $y-intval("30"), imageColorAllocate($image,255,255,255), "pirate-font.ttf", $final_word);
