Question

I want search one string and get related values, but in test the function, in each times search words(Title Or Would Or Post Or Ask) displaying(give) just one output Title,11,11 !!!! how can fix it?

  // test array
  $arr = array('Title,11,11','Would,22,22','Post,55,55','Ask,66,66');
  // define search function that you pass an array and a search string to
  function search($needle,$haystack){
    //loop over each passed in array element
    foreach($haystack as $v){
      // if there is a match at the first position
      if(strpos($needle,$v) == 0)
        // return the current array element
        return $v;
    }
    // otherwise retur false if not found
    return false;
  }
  // test the function
  echo search("Would",$arr);

The issue lies in strpos. http://php.net/manual/en/function.strpos.php
The haystack is the first argument and the second argument is the needle.
You should also do a === comparison for getting 0.

// test array
$arr = array('Title,11,11','Would,22,22','Post,55,55','Ask,66,66');
// define search function that you pass an array and a search string to
function search($needle,$haystack){
  //loop over each passed in array element
  foreach($haystack as $v){
    // if there is a match at the first position
    if(strpos($v,$needle) === 0)
      // return the current array element
      return $v;
  }
  // otherwise retur false if not found
  return false;
}
// test the function
echo search("Would",$arr);
