Problem with explode()?

[jj20051]

I have a script that connects to another server to pull data... When it pulls the data it comes back in the following format:

 

t1.sh t2.sh t3.sh test.sh 

 

However using the code bellow does not separate it like it should, it should put one file per line but I think I did something wrong...

 

// Pulls the output from the server:
$var_test = $ssh->exec('./test.sh');
// Explodes it...
$var_test2 = explode(" ", $var_test);
// Echos it one per line...
foreach ($var_test2 as $variable) {
echo '<br>'.$variable;
}

What is it actually outputting?

[jj20051]

Its outputting the following in html:

 

<br>t1.sh
t2.sh
t3.sh
test.sh

 

Which means it thinks there is only one row in the array or something?

What are you actually trying to accomplish?  Because, aside from the visible <br> that's before t1.sh, it looks like it's working properly.

There should be a "<br>" before each file name. I suspect the data is split by new line feeds, not spaces. That could explain the results you're seeing.. try splitting by this instead:

 

preg_split('/(\n|\n\r)/', $var_test);

 

That will use a regular expression to split the string on either "\n" (Linux format line-feed) or "\n\r" (Windows format).

Thank you Adam... that did exactly what I was looking for it to do It appears that linux sends back the \n even though it looks like a space...

[Adam]

Browsers will convert any whitespace (tabs, new-lines, etc.) into a single space when rendered. If you look at the data into the source it will be new lines.

Whoops made a little mistake with the line-feed characters; should be "\r\n", not "\n\r".
