[SOLVED] whats this white space, like a tab but not?

[jesushax]

hi all the below is copied from my source

 

12345687 	   

 

if you copy it then start deleteing after 4 deletes it jumps like a tab space, but i tired a str_replace to remove the tab spacing didnt work

 

function NoSpaces($text) {
$text = str_replace("	","",$text);
return $text;
}

[Mchl]

Try removing \t (that's backslash+t). It's escape sequence for tab.

[jesushax]

no still didnt work, could it be something else not a tab?

[Mchl]

Perhaps you could just use trim?

[jesushax]

yeah i did, but trim only removes 1 trailing and leading space doesnt it

 

that example text has 4 spaves and some wierd tab:|

 

i tried both no luck

 

$text = trim($text);

$text = str_replace("\t","",$text);

[jesushax]

right ive just copied that dodgy text into a page now and im trying everything to get rid of it

 

i even copied and pasted the whole gap into the str_replace and that didnt work :|

 

<?php
$data = "12345687 	   ";

str_replace(" 	   ","",$data);

echo $data;
?>

[Yesideez]

Are you saying there's spaces/tabs/something on the end of the numbers or something appearing above/below them as well?

[kenrbnsn]

This

<?php
$data = "12345687 	   ";

str_replace(" 	   ","",$data);

echo $data;
?>

willl not work, since you don't change the value of $data.

 

This

<?php
$data = "12345687 	   ";

$data = str_replace(" 	   ","",$data);

echo $data;
?>

 

or

 

<?php
<?php
$data = "12345687 	   ";

$data = str_replace("\t","",$data);

echo $data;
?>

 

Should.

[jesushax]

ah yes, whoops my bad i knew that

 

the /t worked seems it was a tab after all

[jesushax]

what is a space in the same format as the /t for tab

[kenrbnsn]

There is no special representation for a space. And its "\t", not "/t" for a tab.  For a complete list see this section in the manual.

[jesushax]

hmm well the text seems to still have some sort of spacing character in there

 

<?php
$text = "12345687 	   ";

$text = str_replace("\t","",$text);
$text = str_replace("  ","",$text);
$text = str_replace("   ","",$text);
$text = str_replace("    ","",$text);
$text = str_replace("     ","",$text);
$text = str_replace("      ","",$text);
$text = str_replace("       ","",$text);
$text = str_replace("        ","",$text);

echo $data;
?>

 

gives me the below

the tabs gone but theres still spacing if you highlight it, what can this spacing be?

12345687    

[Yesideez]

$len=strlen($text);
for ($i=0;$i<$len;++$i) {
  echo 'Position '.$i.':'.ord($text[$i]).'<br>';
}

 

Run that and post the output - I'd LOVE to know what those spaces are.

[jesushax]

it gave back this

 

Position 0:49

Position 1:50

Position 2:51

Position 3:52

Position 4:53

Position 5:54

Position 6:56

Position 7:55

 

what does this mean?

[Yesideez]

Now look those values up in an ASCII chart

 

49=1

50=2

51=3

52=4

53=5

54=6

56=8

55=7

 

I was hoping the space(s) would show up or are you passing it the trimmed string? It needs to be passed the string with the spaces on the end.

[Daniel0]

What exactly are you trying to do?

 

You can do

$string = preg_replace('#\s#', '', $string);

to replace all whitespace (tabs and spaces included).

[jesushax]

well heres the code that make this happen

 

form data goes to register.php

 

register.php

$_SESSION["PostData"] = $_POST;

 

so i can recall the form data if the users gets redirected becuase of an errror, eg. they havent put in a required field

 

so when the user is redirected back to regform

 

regform.php

$post = $_SESSION["PostData"];

<input name="Sect1_6" type="text"size="30" value="<?php echo NoSpaces($post["Sect1_6"]);  ?>
   " <?php
   if($error == "email") {
   echo 'style="border:1px solid #FF0000;"';
   } 
   ?> 
       />

 

no spaces function

function NoSpaces($text) {
$text = str_replace("\t","",$text);
$text = str_replace("  ","",$text);
$text = str_replace("   ","",$text);
$text = str_replace("    ","",$text);
$text = str_replace("     ","",$text);
$text = str_replace("      ","",$text);
$text = str_replace("       ","",$text);
$text = str_replace("        ","",$text);

return $text;
}

 

and in that field i have the value

12345687  

 

which has those wierd spaces trailing it, we got rid of the tab not theres these smaller spaces that look just like spaces but there not?

 

 

 

[Daniel0]

Read my reply above.

[jesushax]

i tried that, it didnt get rid of any of them :|

 

also that would remove space if a user has put space between a word which we need to keep

[Yesideez]

What does strlen() result in giving on the string WITH spaces?

[jesushax]

awww bloody hell im such an idiot lol

 

it was working just my code for my form field...

 

i had it like

 

<input name="Sect1_5" type="text" size="15" value="<?php

  if($action == "edit") {

  echo $row["Sect1_5"];

  } else {

  echo NoSpaces($post["Sect1_5"]);

  }

  ?>

  "  />

 

leaving spaces after the value has been posted, god dammit lol

 

sorry for wasting your time :| sowiiiiiii!

 

THanks

[Yesideez]

LOL

 

It happens to all of us at some time
