Question

This is an XML question.

Modify the following PHP script to find strings anywhere in the words:

<?php

$q = strtolower($_GET[“q”]);

if (!$q) $q = “ama”; # silly default for testing more easily

$items = file(“entries.txt”, FILE_IGNORE_NEW_LINES);

if (!$items) return; # file not found

if (!$items[0]) return; # file was empty

$maxitems = 30; # too many completions...

$n_found = 0; # number found so far

# look for titles starting with $q

foreach ($items as $key => $value) {

$where = strpos(strtolower($value), $q);

if ($where !== false && $where == 0) {

echo “$value\n”;

if (++$n_found > $maxitems) {

return;

}

}

}

?>

Solution:

-----------------------------------------------------------------------------------

<?php                       /* Start tag */

$q = strtolower($_GET[“q”]);    /* Converting string to lower case .. */          

if (!$q)

      $q = “ama”; # silly default for testing more easily   /* Assigning data.. */

      $items = file(“entries.txt”, FILE_IGNORE_NEW_LINES); /* Opening file.. */

if (!$items)                 /* Condition checking for successfull opening of file.. */

          return; # file not found        

if (!$items[0])          /* Condition checking.. */

        return; # file was empty

$maxitems = 30; # too many completions...

$n_found = 0; # number found so far

# look for titles starting with $q

foreach ($items as $key => $value) {

       $where = strpos(strtolower($value), $q);

if(where.exists($q))        /* To find strings anywhere in the words.. */

           echo “$value\n”;

       else if (++$n_found > $maxitems) {

         return;

     }

   }

}
