Question

Good day, I need to find with a regular expression all matching elements in an array using PHP, but I have a bug.

<?php
$a[0]='[e-mail]';
$a[1]='[e-mail]';
$a[2]='[e-mail]';
$a[3]='___@.user';
$pattern = '[a-z_0-9]+@[a-z]*.[a-z]{2,}';
for ($i=0;$i<=3;++$i)
{
    if(preg_match($pattern,$a[i]))
    {
        echo $a[i];
    }
}

Warning: preg_match() [function.preg-match]: Unknown modifier ‘+’ in {path to file} on line 9

Thanks.

You can try this-

$a[0]='[e-mail]';
$a[1]='[e-mail]';
$a[2]='[e-mail]';
$a[3]='___@.user';
for ($i=0;$i<=3;++$i)
{
  if (!preg_match("/^[-_\.a-z0-9]+@([-_a-z0-9]+\.?)*[a-z]{2,6}$/i", $a[$i])) {
      return false;
  }
return true;
