Need To Find Email Addresses From a File

knashash

Hello....I need to open a file, read it line by line (this part I can do no problem)

Then I need to see is there is an email address in each line of the file. There can possibly be more than one email address in each line. I need to find those email addresses (I guess with regular expressions?) and then save them into variables for later viewing.

My problem is regular expressions. I have no idea how to do this, can someone please help.

Thanks in advance.......😕

Search the forum for email regex

That solution requires you to have each email address on a sepaerate line, what if there was no way to splt them up into different lines. Is there a way to just loop through a text file and pull out each email without breaking it up into seperate lines?

Then instead of [man]preg_match[/man] you can use [man]preg_match_all[/man], yeah?

Here is the solution I used if anyone is interested:

To extract multiple email addresses from a file you can use the following code:

$file1 = "Your File";
if (!($removeFile = fopen($file1, "r"))) exit("Unable to open the list file.");
$z = 0;
$file_array = array();
while (!feof ($removeFile))
{
$buffer = fgets($removeFile, 5000);
if (preg_match('/\b[A-Z0-9.%-]+@[A-Z0-9.%-]+.[A-Z0-9._%-]{2,4}\b/i', $buffer, $matches))
{

$file_array[$z] = $matches[0];
}
$z++;
//echo $buffer;
}

The above code reads through a file line by line and takes whatever matches it finds and places in to a useable array.
