Removeing blank spaces

426 Contributor
I have some values in an array and I need to remove the blank spaces before them.
I've used
Expand|Select|Wrap|Line Numbers
  1. array_walk($context_array, 'trim_value');
To trim the spaces using the function:
Expand|Select|Wrap|Line Numbers
  1.   function trim_value(&$value)
  2.   {
  3.     $value = trim($value, "\xC2\xA0");
  4.   }
This seems to have no effect. I need to convert my values into an array of single characters. I don't have PHP 5 so I've used a function to do the same job as str_split.

Expand|Select|Wrap|Line Numbers
  1.   //This fuction is almost the same as the fuction str_split included in php5.
  2.   function strsplt($thetext,$num)
  3.   {
  4.     if (!$num)
  5.     {
  6.       $num=1;
  7.     }
  8.     $arr=array();
  9.     $xfive=floor(strlen($thetext)/$num);
  10.     while ($ifive<=$xfive)
  11.     {
  12.       $yfive=substr($thetext,$jfive,$num);
  13.       if ($yfive)
  14.       {
  15.         array_push($arr,$yfive);
  16.       }
  17.       $ifive++;
  18.       $jfive=$jfive+$num;
  19.     }
  20.     return $arr;
  21.   }
However when I get the result for the blank space are not removed and for sections where I've used   it has changed it to  which means I get wired looking symbols. Can anyone suggest what it happening?

I'd like to know why this happened. I've fixed it chanigng the trim function to this:
function trim_value(&$va lue)
$value = trim($value, " , ");

I'd like to fix it proerly though.

Hello. I am trying to read a small text file using the readline statement. I can only read the first 2 records from the file. It stops at the blank lines or at lines with only spaces.
