A newbie question.

[jambojim]

I am currently editing a PHP script I located on the internet. I have created a multi-line file that inputs to the screen. I am using the following command:

$output=readfile($file);

The command works just fine. My problem is I don't want all of the information within the file to display. Two of the lines of information are a phone number (phone) and an email address (email). How do I go about suppressing the phone and email information so it remains in the file, but does not display on the screen?

Thank you for any assistance you may provide.

Do you want everything in the file to be output to the browser? Maybe you'd be better of with file_get_contents [us2.php.net].

Hey, what you can do is you can use fgets to get every line one by one from your file and put a check, if any line contains the information which you dont want to show u dont echo it

<?php
$file = fopen("yourfile.txt", "r") or exit("Unable to open file!");

while(!feof($file))
{
$thisLine=fgets($file);
//check $thisLine variable here, either with
//regular expression or strpos to see if this
//line contains email or phone number
// and if not, set $canShowThisLine to true;
if($canShowThisLine)
{
echo $thisLine;
}
}
fclose($file);
?>

Or check this

Check Last Message from jshpro2, you just need to invert his "if" so that if your line matches the regex you dont echo and if it doesnt, you echo.

Thank you to all who have offered solutions to this problem, thus far. I thought that by posting the code in question it would help to answer my question. There is an HTML page that this code works with. Please let me know if I should post that info, too.

Now, I am TRULY a newbie at this, so I must admit the solutions provided don't make a lot of sense to me - yet! Can anyone inform me just how I may incorporate their solution in the existing code?

Thanks, again, folks.
