Hi,
Is there a function in php that makes it possible to limit the output of a
text-string; meaning only print the first e.g. 20 characters of the string?

Have you bothered to look at string functions in the documentation? http://www.php.net/manual/en/function.substr.php

Yes, I have looked in the manual but I'm sure that I'm not the first person
to get a bit confused trying to look up a certain solution in the php.net
manual. It is very hard to find the needed function when you don't know what
to look for!
You know what I mean?

substring your string starting at 0 and going for 20 and then echo the
result.
eg.
$newstring = substr($oldstri ng,0,20);
echo $newstring;

You can also do this in a single step:
echo substr($oldstri ng,0,20);
Two advantages of consolidating statements in order to eliminate temporary
variables are:
1). fewer lines of code and variables to analyze in the future when it is time
to make changes to the program, and
2). it is more efficient since the PHP runtime doesn't have to create a
variable and load it every time the program runs. The benefits are both
faster execution speed and more compact programs. You can also do this in a single step:

I see your point! Thank you;-)

Greetings to the Python gurus,
I have a binary file and wish to see the "raw" content of it. So I open
it in binary mode, and read one byte at a time to a variable, which
will be of the string type. Now the problem is how to print the binary
format of that charater to the standard output. It seems a common task
but I just cannot find the appropriate method from the documentation.
Thanks a lot.

Hi,
I have a question about std::wcout and its underlying C functions.
According to C99, a stream have an orientation type that is one of
byte-oriented or wide-one, and it is determined by the first using C
function on that stream. And the specific orientation functions should
not be applied to the stream that have other orientation.

print and softspace in python
In python, whenever you use >>>print statement it will append a
newline by default. If you don't want newline to be appended, you got
use a comma at the end (>>>print 10,)
When, you have a list of characters and want them to be printed
together a string using a for loop, there was observation that no
matter what there was space coming between the characters. No split
or join methods helped.
print e,
a b c

I hate to tell you this, but "%6s" in C does NOT print 6 strings. It
prints 1 string, right justified, in no less that 6 characters.
