Question

我正在尝试连接此代码，但我无法正确执行

echo '<input type="text" id="text" name="username" 

value=".<?php if(isset($_COOKIE['.'rememberme'.']))

{echo $_COOKIE['.'remember me'.'];}?>." 

placeholder="Username"/><br />';

Answer 1

你已经在PHP那里了......

<?php
echo '<input type="text" id="text" name="username"';
if( isset($_COOKIE['rememberme'])) echo ' value="'.htmlspecialchars($_COOKIE['rememberme']).'"';
echo ' placeholder="Username" /><br />';

Answer 2

printf('<input type="text" id="text" name="username" value="%s" placeholder="Username"/><br />', 
    (isset($_COOKIE['remember_me'])) ? htmlspecialchars($_COOKIE['remember_me']) : ''
);
