explode an array php not working

Question

I don't understant why my explode doesn't work :

I have an array :

array(6) { 
[0]=> string(0) "" 
[1]=> string(21) " Subject Hello World " 
[2]=> string(57) " Bonjour se jserais base sdf sdf sd f sqdf qsfd " 
[3]=> string(22) " [email protected] " 
[4]=> string(12) " hello byee " 
[5]=> string(11) " loul fund " }

I want to creat an another tab for element 4 an 5. I try an

$one = explode(" ", $this->connect[4]);
var_dump($one);

But the result is :

array(1) { [0]=> string(12) " hello byee " }

and not :

array(1) { [0]=> string(4) "hello" [1]=>string(4) "byee" }

Do you no why ?

Technically your array should consist of 4 elements because you have two spaces surrounding each string. Use trim() to remove those. — silkfire

Are those spaces in the string or some other form of white space? — Tim Withers

just for fun, if you want to be sure it is indeed not a space, just do "var_dump(ord($this->connect[4][0]));" I am guessing it will not say it is "32" — nvanesch

Unexpected. that is actually a linefeed. Not any type of whitespace. — nvanesch

please try this

  $parts = preg_split('/\s+/',$this->connect[4]);
  print_r($parts);

$parts = preg_split('/\s+/',trim($this->connect[4])); work ! :) Don't understand why explode not... an idea ?

@MartialE the one which you have used is also working for me thats why i have given you alternate solution.

@MartialE \s matches any whitespace character. It must have been some sort of other whitespace character.

@AbsoluteƵERØ there is a function to see the special character?

Thus, MartialE, in this case, explode("\n", $this->connect[4]) would have worked =)

Working example at http://codepad.org/0uMXe9Js.

<?php
$connect = array(
    '',
    ' Subject Hello World ',
    ' Bonjour se jserais base sdf sdf sd f sqdf qsfd ',
    ' [email protected] ',
    ' hello byee ',
    ' loul fund '
);

print_r(explode(' ', $connect[4]));
print_r(explode(' ' , trim($connect[4])));

Output:

Array
(
    [0] => 
    [1] => hello
    [2] => byee
    [3] => 
)
Array
(
    [0] => hello
    [1] => byee
)

The problem must be in your array values, are you sure those are really spaces? Use PHP ord function to check them out.
