我不知道这个代码有什么问题,这是一个错误,或者我在某个地方犯了错误; xDebug什么都没显示.
class theme {
function theme() {
//show header (meta, style, htmldoctype, script, and title)
$this->htmlheader();
//show main content
//show footer
}
function htmlheader() {
require "localsettings.php";
echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01//EN\" \"http://www.w3.org/TR/html4/strict.dtd\">\n<html>\n<head>\n";
echo "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">\n";
echo "<title>$site_name - $page_title</title>\n";
echo "</head>\n";
}
}
require "theme.class.php";
$html = new theme();
//display result
$html->theme();
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

当您将该函数命名为与该类相同时,它是一个"构造函数",并在实例化该类时被调用.因此,您的函数theme()在这里被调用:
$html = new theme();
和这里:
$html->theme();
删除后者,你应该好好去.
