$titles[] = "Possible Title 1";
$titles[] = "Possible Title 2";
$titles[] = "Etc. Etc.";

 srand ((float) microtime() * 10000000); // Seed the random number generator

echo $titles[array_rand($titles)]; // Pick a random item from the array and output it
?></title>
<meta property="og:title" content="<?= $titles[array_rand($titles)] ?>" />
</head>
<body>
</body>
</html>

<meta property="og:title" content="<?=$titles[0]?>" />

Answer 3

使用此代码（我已为您编辑代码）

<?php

        $titles = array();

        $titles[] = "Possible Title 1";
        $titles[] = "Possible Title 2";
        $titles[] = "Etc. Etc.";

         srand ((float) microtime() * 10000000); // Seed the random number generator

        $titles[array_rand($titles)]; // Pick a random item from the array and output it
        ?>



        <html>
        <head>
        <meta property="fb:app_id" content="366632706686339" />
        <meta name="twitter:card" value="summary"> 
        <meta property="og:title" content="<?=$titles[array_rand($titles)];?>" />
        <meta http-equiv="refresh" content="0">
        <title><?=$titles[array_rand($titles)];?></title>
        </head>
        <body>
        </body>
        </html>
