Question

我尝试输出字符串以进一步创建HTML文件，但我无法弄清楚如何使字符串正常工作。没有功能的部件工作正常，但这些功能不起作用......

我的代码：

$stringData = "";
$stringData .= "
<!DOCTYPE html>
<html xmlns='http://www.w3.org/1999/xhtml' dir='ltr' lang='cs-cz' xml:lang='cs-cz'>
  <head>
    <link rel='stylesheet' type='text/css' href='out_styl.css'>
    <link rel='stylesheet' type='text/css' href='reset.css'>
    <meta http-equiv='content-type' content='text/html; charset=UTF-8' />
  </head>
  <body>
    <div class='stranka'>
        <div class='part'>
            <h1>Denní nabídka - pondělí</h1>
            ";
                $stringData .= jout("0,2 l", vp_u($dat_po, "pol", "nazev"), vp_u($dat_po, "pol", "cena") . ",-");
                $stringData .= "<span>Menu 1.</span>";
                $stringData .= jout("0,2 l", vp_u($dat_po, "pol", "nazev"), "");
                $stringData .= jout(vp_u($dat_po, "hlj", "gramaz") . " g", vp_u($dat_po, "hlj", "nazev"), vp_u($dat_po, "hlj", "cena") . ",-");
                $stringData .= "<span>Menu 2.</span>";
                $stringData .= jout("0,2 l", vp_u($dat_po, "pol", "nazev"), "");
                $stringData .= jout(vp_u($dat_po, "hld", "gramaz") . " g", vp_u($dat_po, "hld", "nazev"), vp_u($dat_po, "hld", "cena") . ",-");
                $stringData .= "<span>Menu 3.</span>";
                $stringData .= jout("0,2 l", vp_u($dat_po, "pol", "nazev"),"");
                $stringData .= jout(vp_u($dat_po, "hlt", "gramaz") . " g", vp_u($dat_po, "hlt", "nazev"), vp_u($dat_po, "hlt", "cena") . ",-");
            $stringData .= "
        </div>
    </div>
  </body>
</html>
";

感谢您的帮助

试试这个。

ob_start()和ob_get_clean()之间的任何内容都不会显示在浏览器中。相反，它可以存储在变量

中

<?php
ob_start();
?>
<!DOCTYPE html>
<html xmlns='http://www.w3.org/1999/xhtml' dir='ltr' lang='cs-cz' xml:lang='cs-cz'>
  <head>
    <link rel='stylesheet' type='text/css' href='out_styl.css'>
    <link rel='stylesheet' type='text/css' href='reset.css'>
    <meta http-equiv='content-type' content='text/html; charset=UTF-8' />
  </head>
  <body>
    <div class='stranka'>
        <div class='part'>
            <h1>Denní nabídka - pondělí</h1>
                <?php echo jout("0,2 l", vp_u($dat_po, "pol", "nazev"), vp_u($dat_po, "pol", "cena") . ",-"); ?>
                <span>Menu 1.</span>
                <?php echo jout("0,2 l", vp_u($dat_po, "pol", "nazev"), ""); ?>
                <?php echo jout(vp_u($dat_po, "hlj", "gramaz") . " g", vp_u($dat_po, "hlj", "nazev"), vp_u($dat_po, "hlj", "cena") . ",-"); ?>
                <span>Menu 2.</span>
                <?php echo jout("0,2 l", vp_u($dat_po, "pol", "nazev"), ""); ?>
                <?php echo jout(vp_u($dat_po, "hld", "gramaz") . " g", vp_u($dat_po, "hld", "nazev"), vp_u($dat_po, "hld", "cena") . ",-"); ?>
                <span>Menu 3.</span>
                <?php echo jout("0,2 l", vp_u($dat_po, "pol", "nazev"),""); ?>
                <?php echo jout(vp_u($dat_po, "hlt", "gramaz") . " g", vp_u($dat_po, "hlt", "nazev"), vp_u($dat_po, "hlt", "cena") . ",-"); ?>
        </div>
    </div>
  </body>
</html>

<?php
$stringData = ob_get_clean();
?>

关于ob_start();的问题

变量中的函数不起作用
