Ok. This is not a numeral problem? strval did not make a difference.
I have, however, solved the immediate problem with:
# if((strtolower(substr($enquiry, 0, 1)) == $rbenquiry))
if((strtolower(substr($enquiry, 0, strlen($rbenquiry))) == $rbenquiry))
However, preg_replace ('/('.$searchenquiry.')/i' , "<b>$1</b>", $mydata->RB)
still gives me:
error: Unknown modifier ...
$searchenquiry = "1.0.1 Retrospective bibliographies and checklists / bibliographies et
répertoires rétrospectifs";
