I'm trying to achieve the following:
start form entry
user enters form data and submits ($form_data)
preg_match_all data for $pattern, store matches in $match_arr
if one or more matches
display string back to user, with matched substrings in different
color/emphasis
start form entry again
else continue
my initial solution to recontructing the string:
// if 1 match
preg_replace ($pattern,'<em> '.$match_arr[0][0].'</em>',$form_data ,1);
// if multiple matches
preg_replace ($pattern,'<em> '.$match_arr[0].'</em>',$form_data ,-1);
...but the latter doesn't work the way I hoped. When the replace var is
an array $pattern also must be an array for preg_replace to use the
different array values in $replace.
Any ideas how to get around this problem in an elegant manner? Or an
alternative solution altogether? I searched for a function/solution
that tells me at which position preg_match_all( ) found a match, so I
can avoid the preg_replace altogether, but I haven't found any.
cheers,
