PHP regular match backslash '\' and dollar '$', php slash

This example describes the PHP Regular Expression matching method with the backslash '\' and dollar '$. We will share this with you for your reference. The details are as follows:

1. test. php:

<? Php $ content = '2017 <td> 1111111 <\/td> 3 $ '; // '\\\\\\/'100' \ 'escape string 100 '\', the string is '\' // 3rd ''\ 'to escape 4th'' \', which is equivalent to the string '\' // 5th ''\ 'to escape 4th '/', equivalent to the string '/' // character combination as '\/' Two '\' regular expressions as '\' $ pattern = '/<td> ([0-9] {7 ,}) <\\\\\/td> \ d \\$ $/'; $ result = preg_match_all ($ pattern, $ content, $ match_result); if ($ result) print_r ($ match_result); else echo ("not match ");

2. Method 2:

$content = '1111111<td>2222222<\/td>3$';$pattern = "!<td>(\d{7,})<\Q\/\Etd>\d\Q$\E!";$result = preg_match_all($pattern, $content, $m);if($result)  print_r($m);else  echo("not match");

3. Running result:

Array(  [0] => Array    (      [0] => <td>2222222<\/td>3$    )  [1] => Array    (      [0] => 2222222    ))
