Suppose I have some bank spaces in an empty sting, how can I chech the bank spaces and print it is really a empty string.

Thnak you.

    and empty string with spaces, trim($string) will make a blank string with spaces = ""

    $string = " ";
    trim($string) will = ""

      a month later

      Please take a look of the following code. I am getting the output "Different" What kind of string operation I have to do so that I will get "Same". Thank you.

      <?php
$name1 = "     Hello          World        ");
$name2 = "Hello World";

print "Before: $name1<br>";
print "Before: $name2<br>";

if ($name1 == $name2)

print "Same";

else
    print "Different";

?>

        I think the simplest way would be this.

        <?php
$ary_str[0] = "     Hello                World            ";
$ary_str[1] = "Hello World";

$i=0;
foreach ($ary_str as $cur_str) {
  $ary_temp = explode(" ",$cur_str);
  $ary_str[$i] = $cur_str;
  $i++;
}

if($ary_str[0] == $ary_str[1]) {
  echo "The Flux Capcitator Works.";
} else {
  echo "No good idea comes from hitting your head on the toilet."
}
?>

          I think there's also:

          function removeExtraSpaces($str) {
	//remove whitespace from start and end
	$str = trim($str);
	//convert whitespace in between to a single space each
	return preg_replace("/[\\\\n\\\\r\\\\t ]+/", " ", $str);
}

          then you can simply use this function on your strings.

          I used this myself to prevent spoofing of nicknames since extra whitespace is not shown when a page is displayed.

          EDIT:
          hmm... think there's a bug, so fixed it.

            drawmack,

            You code does not give me the right output.

              laserlight,

              Can you please explain me what's going on in the following trick in your code.

              "/[\n\r\t ]+/"

              Thank you.

                They arent really needed here, since \r and \n are the linefeed and newline characters.

                basically, the [chars] specify a group of characters to parse with.
                The + indicates one or more of such a character belonging to this group.
