string concatenation with fgets

Hi all,

I'm trying to append some text to what I read from a file.

My code;

$file = fopen("foo.txt", "r");
while (!feof($file)) {
$line = fgets($file);
print $line."sometext";
}
fclose($file);

foo,txt;
a
b
c
d
e
f
g

And when I run the script, it looks like;
a
sometextb
sometextc
sometextd
....


Any ideas?

Thanks in advance,
- aurf

Re: string concatenation with fgets

Is this what you want

$file = fopen("test.txt", "r");
while (!feof($file)) {
$line = trim(fgets($file));
print $line."sometext\n";
}
fclose($file);

outputs
asometext
bsometext
csometext

Ref to http://us3.php.net/manual/en/function.fgets.php. "Reading ends
when /length/ - 1 bytes have been read, on a newline (which is included
in the return value), or on EOF (whichever comes first). If no length is
specified, it will keep reading from the stream until it reaches the end
of the line. "

Hi,

Sorry, I was incomplete :)

I would like;

asometext
bsometext
csometext

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

So if the file contains

a
b
c

I would like;

asometext
bsometext
csometext...

Re: string concatenation with fgets

So here is my final test code, notice the check for ' ' in the if.

Since I'm on Linux, this has to do with whats between the last LF and
EOF which is nothing but this nothing will get printed out.

$file = fopen("somefile.txt", "r");
while (! feof($file))
{
$names = trim(fgets($file));
if ($names == '')
{
break;
}
print $names."sometext\n";
}
fclose($file);

Re: string concatenation with fgets

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.

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!
