array of file paths putting white space in front of filenames

[dogdaynoon]

Hello, i have the following code: php 5, ms server 2008, iis 7

I pass this script a csv list of file paths like so...

,C:\path\path\path\file.name,C:\path\path\anotherFile.name,C:\path\path\path\file3.file

(yes there is a leading comma in the string for some reason..)

$files = $_POST['files'];

$files = explode(',', $files)
foreach($files as $filename){
if(file_exists($filename)){

echo '":' . $filename .':"Does Exist<br />';

} else {

echo 'Sorry ":' . $filename . ':" Does Not Exist<br />';

}
}

My problem:

the first file path shows it exists and there is no white space in the string, all the file paths after the first one show like such:

 

":C:\path\path\path\file.name:" Does Exist  // 1st path (good)

": C:\path\path\anotherFile.name :" Does Not Exist

": C:\path\path\file3.file:" Does Not Exist

 

pleas note... i put the ": and :" in there to show that there is indeed a white space character in front of and behind the filepaths. EXCEPT for the last path.. there is no trailing white space there.

 

Please explain why you think the white space is being added to these and what i can do to get rid of it.

 

thanks,

dogdaynoon

not enough info/material to give a definitive answer about the whitespace, but is there any reason why you can't just trim($filename) ?

I did try trim, and it had been returning the same results... I went ahead and tried it again, just for good measure and it seems to be working now...

thanks man.
