eregi() function

[KemuriSka]

Hi,

I have an array of potential expletives to filter out of a string submitted by a user. How would I use the eregi() function with my array?

my variables are as follows:

$comments - User submitted string
$expletives - Array of expletives

I have it set up as:

if (!eregi($expletives,$comments)) {
  //code to submit comment;
}else{
  echo "Wash your mouth out you little gimp";
}

I have got it to work with a normal string, but not with an array.

Any help would be appreciated
Thanks
Ste

I don't think you can use an array in there, as you're discovering. (It's not that I'm any expert, but the manual shows a string only....) You will possibly want to loop over each element and check each word individually with foreach or something like that, or read the message content into a string as well as an array, just for the purposes of the 'expletive' check.

HTH,

Unfortunately eregi only works with strings and not arrays

perhaps something like

foreach ($expletives as $value)
{
    if (substr_count($comments,$value) > 0)
    {
        print "Wash you mouth out you little gimp";
        exit;
    }
}

see substr_count for more info.

You could use an array if you used preg_replace(), but then you'd need to massage your list of expletives into PCRE regexps (probably need no more than /.../i around them).

Is there any way to do it using:

[FONT=courier new]$comArray = explode(" ", $comments);[/FONT]

with a foreach() loop and not using eregi()? or is that a bit long winded?

It could be done that way, but it is a bit longwinded. I'd use the preg_replace approach myself (but only 'cos I thought of it).
