Rather than use PHP for this I would look at using the find and sed
tools to edit the files.

The first line is the title of the article and I need it look like
this <title>the name of the article</title>
every file has the first line and the it starts the article on the
second line
The files are in many directory under one main directory
like this
top directory
fashion-school
Dogs
DentalAssistant
etc..........
I need a script that will loop through each directory look at each
file extract the first line and replace it with the example above.
I have figured out how to pull the first line into an array but I
don't no where to go from there to look in each directory and the
write the data back at the top.
$f = file('GENERAL HISTORY OF DOGS.txt');
$a = '<title>' . $f[0] . '</title>';
echo $a;
Something like this should do what you want: http://pastebin.com/jKvAiGYa

If you're running on a *nix system you may want to look at using find, xargs,
and sed. Sorry I can't give you the syntax at the moment but you can google
for the three of them and find several good examples.

The command would be something like this:
find /wwwdir -name \*.txt -print | xargs sed -i s/oldtext/newtext/gi

The issue, as I recall, is that for Python 3, they are changing print
(without parentheses) to require parentheses. This change alone (and
there are others like this in Python 3) will necessitate a *lot* of code
rewrites. Sometimes I wonder about Guido van Rossum.

I tend to do it the way Tedd does, but I'm rethinking this. I recently
had occasion to do a lot of programming in C and Python, and one thing
stood out at me: I can't recall another language which allows
interpolation of variables within strings (without significant diddling,
if at all). It caused me great difficulty because I'm so used to doing
this in PHP. I can convert from '.' to '+' (as in most languages) in my
mind, but embedding variables in strings was a harder habit to break. My
opinion is that the dot operator used this way was a mistake for
PHP. Not using the dot operator to mean "concatenate" would mean we
could use it to replace the accursed '->' for class/method selection.
And the plus operator is obviously a more natural fit for string
concatenation.
And yes, if you're going to use the dot operator, surround it with
spaces for readability.

Hello,
I am trying to run a .sql script produced with mysql-dump from a php script but
failed to find a rudimentary robust solution yet.
mysql_query() can only run one query at a time. Thus its necessary to somehow
parse the input file and separate the queries... which is difficult since the
syntax can be quite complex.
So far I managed to run most CREATE TABLE and INSERT queries just by
dropping newlines (\n) and explode()ing the input by ';'. Now I am stuck with a
CREATE TRIGGER statement because mysql-dump does this:
===
DELIMITER ;;
CREATE TRIGGER ... ON ...
FOR EACH ROW BEGIN ...
...
END;
;;
DELIMITER ;
===
exploding that string by ';' results in 4 (or more) queries which are invalid
syntax then. And I have no glue on what else mysql-dump may come up with on
other occasions.
does anyone know how to do that properly?
I dont favor importing the dumps via shell command like 'cat some.dump | mysql'
either.

Use mysqli - it supports running multiple queries at once.
