Regular expressions question

[creole]

I have a text file of email addresses. The lines look like this:

ivymoe@mindspring.com Email from plus one online Sun 12/31/00 6:22 PM

I would like to get rid of the part in bold, but I don't want to go through all 600 lines by hand. I know that it can be done with regex and indeed I have done lesser thing than this myself. I just can't figure out how to get this one set up.

Anyone have a solution?

which part is in bold? I would do it like this

$file = file("yourtextfile");
for($i=0;$i<count($file);$i++) {
$data[] = str_replace("texttoreplace", "", $file[$i]);
}
$fp = fopen("sametextfile", "w");
for($i=0;$i<count($data);$i++) {
fputs($fp, $data[$i]."\n");
}
fclose($fp);

Sorry bout that folks...forgot about the bold bit. The key is that the date and time at the end changes...it is however, always in the same format.

[freddydoesphp]

$file = file("yourtextfile");
$fp = fopen("sametextfile", "w");

for($i=0;$i<count($file);$i++) {
fputs($fp, substr($file[$i], 0, strpos($file[$i], " "))."\n");
}
fclose($fp);

I figured it out... I had to do it in like 4 steps, but I got it after all...

[freddydoesphp]

Did you try it my way I am positive it is ten times faster than taking ten steps.

I am sure your way would be faster...especially if I was doing it more than once, but for this one time I didn't mind doing it the hard way. It still only took me about 3 minutes...so no big deal.

I know you have already done it, but I decided to write some code anyhow.

<?
$file = "C:\Windows\Desktop\untitled.txt";
$content = implode('',file($file));
$content = preg_replace("/([^\s]*)[^\n]*/","\\1",$content);
$out = fopen($file, "w");
fputs($out,$content);
fclose($out);

print $content;
?>

Freddy, since the date is on the line, I am thinking that each line contains different dates, so having:
str_replace("Email from plus one online Sun 12/31/00 6:22 PM","", $file[$i]);
would only affect one line most likely. Not sure is str_replace() would be the best function to use than, because I don't think it can handle complex string patterns? (I could always be wrong about that though)

Guess you didn't see my second post?? Which would definetly be faster than imploding each line and using preg.
