Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : PHP Script for Combining Words

[Corey Bryant]

I had a client that is looking for a PHP script that outputs words separately & in combination:

For example lets say i have the following words in a text file..

Cat
Dog
Fish

I would paste them into the script and it would then output something like this..

Cat
Dog
Fish
CatDog
CatFish
DogCar
DogFish
FishCat
FishDog

Of course I know about all the script site but trying to even figure out what to search for, I am at a loss.

Thanks!

Well, this would be a pretty complicated script.
First thing would be to put them into an array.
First, you need a Loop that will pass them 1 by 1.
THen a loop that will pass all the word, and have another loop in the second loop that passes all the words and stick them with the first one.

PHP Code:

$wordsarray = array('cat', 'dog', 'fish');
for($x = 0; $x<count($wordsarray);$x++) { echo $wordsarray[$x]."\n"; for($y = 0; $y < count($wordsarray);$y++){echo $wordsarray[$x] . $wordsarray[$y]."\n";}}

Thanks! I'l keep that in mind. Sonicgroup gave me this code & with a few tweaks - it seems to work:

// Text file containing words 
$txt = '/path/to/wordfile.txt'; 

$handle = fopen($txt, 'r'); 

if (!$handle) { 
   die('Could not open...'); 
} 

// set up arrays for storing words and concatenated words 
$words = array(); 
$cwords = array(); 

// get the words 
while (!feof($handle)) { 
   // strip_newlines is not a real function - needs to be implemented 
   array_push($words, strip_newlines(fgets($handle))); 
} 

// while we still have words 
for ($i = 0; $i < count($words); $i++) { 
   // get the current word 
   $curword = $words[$i]; 
   // loop over the words 
   foreach ($words as $word) { 
      // if the word is the same as the current word, skip it - i.e. no CatCat 
      if ($word == $curword) { 
         continue; 
      } 
      // append the concatenated word to the array 
      array_push($cwords, $curword.$word); 
    } 
} 

foreach ($words as $var) echo $var."";
foreach ($cwords as $var2) echo $var2."";
