Hi Shawn,
Your code looks cleaner then mine so i tried it and got the last entry
in the txt file printed twice.

Remove the if statement and just print out $tmp. The while loop is going
over one extra time than you need, and on that final iteration, $tmp is
an empty string. The if statement only changes $name if $tmp is empty,
so it leaves it as it was, hence you getting the last line printed
twice. Printing out an empty string in this example won't do anything,
and the if statement is also pretty useless as it just copies the value
to another variable on a condition that will only result in the
side-effect you've noticed.

Re: [PHP] string concatenation with fgets
Hi Ash,
Actually I need the if because the code will print out an empty line
and add sometext to it.
So without the if check for an empty line, at the end of the loop I'll
get sometext. For example, if the file I am processing called
somename.txt has
a
b
c
in it. I'll have;
asometext
bsometext
csometext
but w/o the if check, I'll also have
sometext
as well.

Then put the print statement inside the if, not the assignation,
otherwise you will always get that last line!

Hi,
Sorry, I was incomplete :)
I would like;

Basically, I would like to add whatever text to the end of what I find

So if the file contains

I would like;
asometext

Re: [PHP] string concatenation from array
Micah,
The sign in PHP (to the best of my knowledge) does not concatenate.
Use a . instead. See below.
$wresult = ;
foreach ($search_string as $word_result){
$wresult .= $word_result;
}
That should work for you.
