PHP code to ignore text

[drsmith]

I have some PHP code that reads in several .csv files. On occassion (since moving to Excel 2007) some extraneous characters/words tend to be introduced which is causing the mail program to fail. I am trying to put something in the code that will allow it to ignore everything except email addresses. Here is what I have right now:

# All
$allList = "";
$fileID = "/u2/text/confCall_Contacts/All.csv";
$handle = fopen($fileID, "r");
if ($handle) {
while (!feof ($handle)) {
$buffer = fgets ($handle, 4096);
$buffer = substr ($buffer, 0, -2);
list ($a, $b, $c, $d, $e, $f) = split (",", $buffer, 6);
$allList = $allList . $e . " ";
}
fclose($handle);

Any ideas how I can get it to just hit on the email addresses in the .csv file?

Thanks

you can use regular expressions to find only strings with valid email addresses. heres something i've come up with.

function validEmail($var){
$pattern = "/^[a-zA-Z0-9-_\.]+@{1}[a-zA-Z0-9-\.]+\.{1}[a-zA-Z]{2,4}$/"; //email pattern
if(preg_match($pattern, $var)){
return true;
}
return false;
}

That will work, thanks for the input.
