转换&到PHP中的撇号

问题描述

我的数据中有很多HTML实体（

既然&< / code>不是HTML 4.01的一部分，在默认情况下，不会转换为'。

在PHP 5.4.0中，来处理不同的语言，每种语言都包含& apos ; 作为一个实体。

这意味着你可以这样做：

  echo html_entity_decode（'They&'re here。'，ENT_QUOTES | ENT_HTML5）; 
  

您将需要 ENT_QUOTES 和双引号）和 ENT_HTML5 （或任何非 ENT_HTML401 的语言标志，因此请根据您的情况选择最适合的语言） 。

在PHP 5.4.0之前，您需要使用：

  echo str_replace（'&';'，''，'他们& 。'）; 
  

My data has many HTML entities in it (&bull; ...etc) including &apos;. I just want to convert it to its character equivalent.

I assumed htmlspecialchars_decode() would work, but - no luck. Thoughts?

I tried this:

echo htmlspecialchars_decode('They're here.');

But it returns: They&apos;re here.

Edit:

I've also tried html_entity_decode(), but it doesn't seem to work:

echo html_entity_decode('They're here.')

also returns: They&apos;re here.

解决方案

Since &apos; is not part of HTML 4.01, it's not converted to ' by default.

In PHP 5.4.0, extra flags were introduced to handle different languages, each of which includes &apos; as an entity.

This means you can do something like this:

echo html_entity_decode('They're here.', ENT_QUOTES | ENT_HTML5);

You will need both ENT_QUOTES (convert single and double quotes) and ENT_HTML5 (or any language flag other than ENT_HTML401, so choose the most appropriate to your situation).

Prior to PHP 5.4.0, you'll need to use str_replace:

echo str_replace(''', "'", 'They're here.');
