问题
how do I use preg_split() to grab the value between [item:1] and [/item:1]$query= [item:1] my content [/item:1];
This isn't working $match = preg_split('/[[item:1][\/item:1]]/', $query);
echo $match[0];
output should be just " my content ".
UPDATE:
$query = ' [page:1]you got page one content[/page:1] [page:2]you got page two content[/page:2] '; // parse function function parse_page($page, $string) { // VERY IMPORTANT STRIP OUT ANYTHING THAT WOULD SCREW UP THE PARSE $string = str_replace(array("\r", "\n", "\t", "\f"), array('', ''), $string); // test the string with the page number preg_match('@\[page:'.$page.'\](.*?)\[/page:'.$page.'\]@', $string, $matches); // return the match if it succeeded if($matches) { return $matches; }else { return false; } } // if page is set then try and obtain it if(isset($_GET['p'])) { // set the returned parse value to a variable $page_dump = parse_page(($_GET['p']), $query); // check to see if the match was successful if($page_dump[1]) { echo $page_dump[1]; }else { echo '0'; } }else { // parse page 1, if no page specified. $page_dump = parse_page('1', $query); if($page_dump[1]) { echo $page_dump[1]; }else { echo 'no page =('; } }
回答1:
You don't want to split the string, you want to capture a pattern. For that, use preg_match
, eg
if (preg_match('@\[item:1\](.*?)\[/item:1\]@s', $query, $matches)) {
echo $matches[1];
}
Edit: Tested and working
Edit2: Added "s" (PCRE_DOTALL) modifier - http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php.
You should really consider a better markup solution (see XML)
