[PHP-DB] Re: preg_match html tags
Do it with one preg_match operation, like so:
preg_match("/(?<=Purpose).+?(?=<\/p>)/", $fpRead, $matches_new);
Your string will reside in $matches_new[0].
EXAMPLE:
$fpRead = "blah blah PurposeThis is the string you are after blah
blah blah blah blah";
preg_match("/(?<=Purpose).+?(?=<\/p>)/", $fpRead, $matches_new);
print_r($matches_new);
EXPLANATION:
(?<=Purpose)
- backward looking assertion. Read as: "Expression immediately following
must match only strings with "Purpose" immediately before."
.+?
- any character, 1 or more, ungreedy. Ungreedy because otherwise it will
match right up to the last possible place it can. You want it to match up
until the next '', not the last ''.
(?=<\/p>)
- forward looking assertion. Read as: "Expression immediately prior must
match only strings with "" immediately after."
Hope this helps.

In that case, may I suggest an alternative method?
$arr=explode(",",lower($data));
if(in_array(lower($search),$arr)))
...
(If you want to use the preg_*: take out the double quotes in your regex,
which do not appear to be delimiting the substrings within variable $data.)

This works only if the list is space delimited because of the \b:
$search = "TheName";
$data = "TheName TheAddress ThePhone";
if (preg_match("/\b$search\b/i", $data))
{ echo "True"; }
else { echo "False"; }
However as your list is now this works:
$search = "TheName";
$data = "TheName,TheAddress,ThePhone";
if (preg_match("/$search/i", $data))
{ echo "True"; }
else { echo "False"; }
