在变量中正确存储 DataURI

Question

可能有更优雅的方式来表达标题，但这是我能想到的最好的方式，因为坦率地说，我觉得自己很傻，因为我不知道答案，甚至不得不问，但这就是你的方式学习了，不用丢人了。

我存储了 dataURI，例如：

通过简单地执行以下操作在变量中：$some_var = "INSERT_ABOVE"; 并且通常工作正常，但我在我现在正在处理的一段代码中发现代码随时中断变量=>datauri使用了我上面显示的方案，但删除了该行，修复了代码。

所以我不确定？为什么？这个特定的 datauri 正在破坏代码， "" QUOTATIONS 中的任何内容都不应该被视为文字字符串吗？是否有最佳实践或者我应该说推荐的方法将 datauris 存储为要通过代码使用的变量，这样它就不会中断？

任何想法 and/or 的建议将不胜感激，TIA。

PS。这不仅仅是因为末尾的反斜杠，还因为字符串本身没有得到尊重，现在它像这样存储到变量中，谢谢。由于标题最准确地描述了所取得的成就，我认为它更合适。

使用Heredoc string quoting。这是在 PHP 中表示字符串的另一种方式。它可以消除您结束引用被字符串数据转义的问题。

  $str = <<<EOD
