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.

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. Paul -- Paul M.

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

Re: [PHP] How to change the first line of a text file
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.

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

[PHP] How to change the first line of a text file
I have around 6000 text files and I need to change the first line on every
one of them.
The first line is the title of the article and I need it look like this
the name of the article
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 = '' . $f[0] . '';
echo $a;

Technically it does have a microscopic speed increase, but unless you're pumping out hundreds or thousands of lines (like in a loop) you most likely won't notice it. In my code, I always try to use the proper quote marks because I *am* dealing with huge tables of data. I've said this a hundred times before, if you can shave off 0.001 from each row, then after 1,000 rows, you've shaved 1 second off the page time. That seems small, but that shit adds up. Caching will help, as the page is already parsed once, so PHP doesn't have to do the work again in many cases. To me, it's a good habbit and costs you nothing to do. The difference is that with " the PHP engine has to pre-process the string and look to see if there's anything interesting it needs to do -- such as replace any $var with their equivalents or \n or whatever else. A ' means to use it as is, so PHP just spits it back out. In my test comparing: $a = 'The answer is ' .$answer; vs: $a = "The answer is $answer;" I ran numerous test using 10,000,000 (10 million) operations each and the results never exceed 1/2 of a second difference, usually around 1/3 of a second. I realize that servers and conditions can change the results, but these results are what my server produced. I also realize there can be special conditions where one should consider speed, but seldom is the case where one needs to be concerned about pre-processing a string. The likelihood that it will present a problem is extremely remote. And these results are with today's speeds -- the difference will be less tomorrow and an order of magnitude less in a couple of years, or less. I guess that what I am trying to say is pick considerations that are significant enough to have real merit. If you can show that your solution can be significantly improved by doing something a certain way, then more power to you. However, simply saying one way is better because it is faster, or uses less memory, doesn't carry the weight it once did. For example, it would have been nice if the net had been based on 8-bit instead of 7-bit, but the people who developed ASCII were concerned about memory. They were right for what they considered important at their time, but those concerns created a larger problem for the industry that followed. The significants of concerns change over time and not realizing that can create problems later.
