PHP的一个语法问题
PHP code<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$contents = file_get_contents($url); if((preg_match_all('/(<h1.>)/iUs', $contents, $match))){$contents = $match[1][0];} else{ (preg_match_all('/(<h1.>)/iUs',$contents,$match)) [color=#FF0000]$contents = $match[1][0];[/color]}</h1.></h1.>
红色那行报错:
Parse error: syntax error, unexpected T_VARIABLE in

探讨
还有一个问题: PHP code if($rows=mysql_fetch_array(mysql_query("select pl_title from pagelinks limit 1,10"))){ $string=$rows['pl_title']; $string1=urlencode($string); } echo $string; $url = "htt……
