Well, then I have a few questions, no regular, see how I solve.
1. Clears all tags in html, leaving only hyperlinks.
I use Strip_tags.
Strip_tags ($data, $tags)
$data is a string, $tags is a reserved label.
Strip_tags ($data, ' <a> '). Finished? Yes, it's that simple.
If I still want to keep ')
2. Intercepts the first match of a string from $STR1 to $str2 in the $str.
function Str_cut ($str, $start, $end) {//Remove first match, most efficient
$content = Strstr ($str, $start);
$content = substr ($content, strlen ($start), Strpos ($content, $end)-strlen ($start));
return $content;
}
3. Intercepts all matches of the string from $STR1 to $str2 in the $str.
function My_ca ($content, $start, $end) {//Remove all matches, do not include start and end strings
$m = Explode ($start, $content);
$a = array ();
$sum = count ($m);
for ($i = 1; $i < $sum; $i + +)
{
$my = Explode ($end, $m [$i]);
$a [] = $my [0];
Unset ($my);
}
return $a;
}
Summary: You just want to sum up more, do not have regular, with PHP functions you can solve most of the problems.
