Web Hosting Talk : Web Hosting Main Forums : Programming Discussion : question about echo/print

[Gem Hexen]

Ok I get a random variable from an array ( a text file) and assign it to $var

then I say

PHP Code:

echo "$var."; 


However, the output is:

hello . (extra space after the variable :/)

HOW can I remove that space?

[Studio64]

PHP Code:

echo $var."."; 


That should do it..

Although... On second thought the extra " " could actually be included in the $var string itself... Instead of what you believe could be "hello" could actually be "hello "...

[Gem Hexen]

No the string is "hello".

echo $var.".";

did not solve the problem :\

ok it has something to do with reading it from a file. It only has an extra space if its out of the file

so my question now is:

how do I remove the last character from a string?

[Studio64]

PHP Code:

$var = trim($var); 


trim(string str)
This function strips whitespace from the start and the end of a string and returns the stripped string. The whitespace characters it currently strips are: "\n", "\r", "\t", "\v", "\0", and a plain space

Hey since you're really on a roll, is there a way to display the text output from a php script on another server that doesn't have php? Or have the php script output the text in a way that it can be included on a page on this other server as text?

[Studio64]

PHP Code:

$filename = "output.txt";
$handle = fopen($filename, 'a+');

fputs($handle, $text_to_be_written);

fclose($handle); 


Make sure the file has writeable attributes....

If you want a new line after each item included

PHP Code:

$text_to_be_written."/n"=$text_to_be_written 


Glad to help ya out but, it's about 3am now...
I have about 13 beers tonight and I have class in the morning...
Hope I've been of some assitance...

[edit]
err... I missed the other computer part...

Umm.. You could map a drive or alias to the other drive to the other computer to write to....

I have no clue if my last comment makes sense now. I'll figure it out during REM sleep.....
