Modify this as you need...

function xhtml_entities($text0)
{
$bb1 = array('&');
$xml1 = array('&');

$bb2 = array('<', '>');
$xml2 = array('&#60;','&#62;');

$text1 = str_ireplace($bb1, $xml1, $text0);
$text2 = str_ireplace($bb2, $xml2, $text1);

return $text2;
}

Do you want all spaces converted? If so:

$str = 'a string with spaces';
$str = preg_replace("/ /", '_', $str);
echo $str;

Hi all,

I did this just last night! This does the job fine:-

Str_replace(" ","_", $data);

That returns your string as you would expect it too :)

It may be wise to prevent the input containing underscores here too - as you won't be able to convert it back.

$string = str_replace(array('_', ' '), array('', '_'), $input);

Although if I'm honest I'm not sure that won't cause issues... May be best to do:

$string = str_replace('_', '', $input);
$string = str_replace(' ', '_', $string);
