Trim() not working on development server

[ste1986]

Hi,

 

I've got a very weird problem! I'm writing a script that will manipulate some pasted text... most of the code uses trim() to clear characters/words from the beginnings of lines. It doesn't work on it's own trim($string) or with the seperate argument trim($string , "text").

 

The code is fine, it works ok one of our paid for hosting servers (pre-configured), but it won't work on either of our dev servers! All are using Apache. Version info:

Hosting Server (Linux - works)... PHP 4.4.6

Dev 1 (Linux - doesnt work)... PHP 4.3.9

Dev 2 (Windows doesnt work)... PHP 5.2.1

 

It's stumped me! I always assumed that something as simple as trim() would be enabled by default. Can anyone shed any light?

what errors (if any) are you receiving?

 

What code are you using?

If you are facing a prb because of a version then try this code

 

function trim_str($str){

if(strlen($str) > 0){

$str = preg_replace("/^\s+/","",$str);

$str = preg_replace("/\s+$/","",$str);

return $str;

}

return $str;

}

echo "This is trimed string".trim_str('  test  ');

This is in javascript

<script language="javascript">

function trim()

{

if (this.length > 0)

{

var retstr = this.replace(/^\s+/,"");

retstr = retstr.replace(/\s+$/,"");

return retstr;

}

else return this;

}

</script>

both of those solutions have their own problems.

 

Let's try actually fixing the problem..

No errors at all, just not changing the output... Sloppy code so don't laugh

 

$text1 = "Loads of view
multi line
code etc
etc etc
etc etc"
$text2 = strtok("$text1" , "\n");

$count = 1;
while($count <= 10) {
Print($text2 . "<BR>");
/* $list1 = $list1 . "'" . $text2 . "', "; */
$array1[$count] = $text2;
$text2 = strtok("\n");
$count = $count + 1;
}
$result1 = $array1[1];
$result1 = rtrim($result1, "view");

Print($result1."<br>");
Print($array1[2]."<br>");
Print($array1[3] ."<br>");
Print($array1[4] ."<br>");
Print($array1[5] ."<br>");
Print($array1[6] ."<br>");
Print($array1[7] ."<br>");
Print($array1[8] ."<br>");
Print($array1[9] ."<br>");
Print($array1[10] ."<br>");

 

So in that one, I just want it to trim the word view from the first line, but it doesnt do it on my dev servers...

[Jenk]

rtrim() only trims from the end of string (i.e.

$var = rtrim("view some text view", "view"); echo $var; //outputs "view some text"

) - is that what you want?

[ste1986]

In this instance yes, just text from the end of the file. It does the same if I use trim() as well.

 

Sorry for the code, it's from a file I've just been using to test different methods.

[Jenk]

No problem.. I was checking you were not expecting rtrim() to do what trim() does is all.

 

Try echoing the native value inside of tokens (e.g. ")  before echoing the trim'd value to compare. Chances are the end of the string does not match so it's not trimming.

[ste1986]

Before trim, it outputs (with my data in):

<br>Chris, Atkins     view
<br>

 

There's no space at the end of the line, just a carriage return I'm assuming. So doing rtrim($text, "view") should remove it?

[ste1986]

Panic over! Sorry to waste your time guys... it looks like it was either a problem with my code or the text I was pasting in!

 

I changed it to:

$result1 = trim($result1);
$result1 = trim($result1, "view");
$result1 = trim($result1);

 

It now works fine... weird that it worked ok on the other server though! Must just be a random setting. I'll post back if I figure out what the setting is! Thanks again
