不止一个 str_replace 实例破坏了 php 代码答案

【问题标题】：More than one instance of str_replace breaks php code不止一个 str_replace 实例破坏了 php 代码

【问题描述】：

我正在使用 phpmailer，并根据我的需要对其进行了定制。 $templatemessage 内部是给客户的消息，字段为 {name} 和 {fuel}。

这两个字段被 str_replace 函数替换。

在这个问题出现之前，我只是用 str_replace 替换了 {name}，这很好用，将人名导入到那个地方。当我添加额外的 str_replace 函数以将 {fuel} 替换为 $templatemessage 值时，问题就出现了。现在发生的是 {fuel} 值被导入，但它似乎对 {name} 函数做了一些事情，因为它不再导入名称，而是在电子邮件中只显示 {name}，就像我之前添加 {燃料} 它奏效了。怎样才能让两人好好相处呢？

                              $templateData = mysql_fetch_object($templatequery);

                              $gasoiluserTemplate = $templateData->gasoilusers;
                              $dervuserTemplate = $templateData->dervusers;

【解决方案1】：

我会先试试这个：

$mailer->Body = str_replace(array('{name}', '{fuel}'), array($name, $templatename), $textBody);

来自docs

如果搜索和替换是数组，那么 str_replace() 取一个值从每个数组中，并使用它们来搜索和替换主题。如果 replace 的值比 search 少，则使用空字符串其余的重置价值。如果 search 是一个数组并且 replace 是一个字符串，则此替换字符串用于搜索。但是，反过来就没有意义了。

如果搜索或替换是数组，它们的元素首先被处理为最后。

感谢您的帮助，效果很好，我只需要将模板名改为 $templatename，但除此之外它还可以与上述内容一起使用 :-)

【解决方案2】：

问题是你的代码：

//Here you set $mailer->Body = $htmlBody (while replacing {name})
$mailer->Body = str_replace('{name}', $name, $htmlBody);
// the line below is the new one I have added
//Here you set $mailer->Body = $htmlBody (while replacing {fuel})
$mailer->Body = str_replace('{fuel}', $templatename, $htmlBody);

问题是你在第二个str_replace() 中覆盖了 $mailer->Body 你需要做的是使用 $mailer->Body 而不是 $htmlBody

$mailer->Body = str_replace('{fuel}', $templatename,$mailer->Body);

更好的解决方案是上面发布的（使用带有 str_replace() 的数组），但我想指出代码中的实际错误。
