[Problem] PHP function not working...

Hello guys,

I have been working over the following script to check if a particular word is a noun or not.

For this , I open a file with lot of words in it and for each of the word, a check is made

using if , if the the word in dictionary is similar to the word in argument .

I think, for the purpose , this script is alright.

But it is still returning false true everytime.

Can you help me out with the issue?

Following is the link to the dict.txt

<?php
error_reporting(8191);
if(checkNoun('test')) {
  echo 'noun';
}
else {
  echo 'not a noun';
}
print_r(error_get_last());
function checkNoun($a) { // check if the $a is noun
  $u=array(); // variable for testing
  $d=file('dict.txt'); // load the dictionary
  foreach($d as $k => $j) { // for each word in the dictionary ...
    if($j==$a) { // if the word is the one which is argumented , then... 
      array_push($u,'y'); // ... push it in array
    } 
    else { // if it is not the word ...
       // then do this...
    }
  }
  if($u['0']=='y') { // if even the first key of array is filled , then return false
    return false;
  } 
  else { // or return true
    return true;
  }
}
?>

The function replies true everytime , sorry for that , it was a silly mistake! And I am unable to edit the actual post!

 

How about the following function.

if(checkNoun('test')) {
  echo 'noun';
}
else {
  echo 'not a noun';
}



function checkNoun($str){
$file = file('dict.txt');

foreach($file as $line){
   $words = str_word_count($line, 1);
   if(array_search($str, $words)){
      return true;
   }   
}
return false;
}

Thanks for your reply , but , won't this code return true for each dictionary word checked ? And yes I think , it is something related to \n in the $line variable that is preventing the script from functioning ... isn't it? The light flashed into my mind after using str_replace("\n","",$line); !!

 

Add trim out the \n \r

function checkNoun($str){
$file = file('dict.txt');

foreach($file as $line){
   $words = str_word_count($line, 1);
   $escape_words = array_map("trim", $words);  //<--- we trim out the \n \r 
   if(array_search($str, $escape_words)){
      return true;
   }   
}
return false;
}

That should work.
Another alternative could be you read the file line by line and than compare words using strcmp
