A syntax related to PHP

PHP syntax: PHPcode $ contents = file_get_contents ($ url); if (preg_match_all ('/(& lt; h1. * & lt; \/table & gt ;) /iUs ', $ contents PHP syntax

PHP code

  $contents = file_get_contents($url); if((preg_match_all('/()/iUs', $contents, $match))){$contents = $match[1][0];} else{    (preg_match_all('/()/iUs',$contents,$match))    [color=#FF0000]$contents = $match[1][0];[/color]}

The Red Line reports the following error:
Parse error: syntax error, unexpected T_VARIABLE in

I want to capture part of the webpage information. There are two types of frameworks on the webpage, and the regular expressions are the two types. so I want to make a judgment, if it is not the first framework, the second regex is used to capture webpage information.

$ String1 = urlencode ($ string );

$ Url = "http: // localhost/index. php/". "$ string1 ";
$ Contents = file_get_contents ($ url );
If (preg_match_all ('/()/iUs', $ contents, $ match )))
{
$ Contents. = $ match [1] [0];
}
Else
{
(Preg_match_all ('/()/iUs', $ contents, $ match ));
$ Contents. = $ match [1] [0];
}
}

If ($ rows = mysql_fetch_array (mysql_query ("select pl_title from pagelinks limit 1, 10 "))){

}
Echo $ string;
$ Url = "htt ......
