还有一个PHP示例，将显示多行匹配：
<?php$file = 'somefile.txt';$searchfor = 'name';// the following line prevents the browser from parsing this as HTML.header('Content-Type: text/plain');// get the file contents, assuming the file to be readable (and exist)$contents = file_get_contents($file);// escape special characters in the query$pattern = preg_quote($searchfor, '/');// finalise the regular expression, matching the whole line$pattern = "/^.*$pattern.*$/m";// search, and store all matching occurences in $matchesif(preg_match_all($pattern, $contents, $matches)){ echo "Found matches:n"; echo implode("n", $matches[0]);}else{ echo "No matches found";}
