PHP explode()不适用于" -"特点 [英] PHP explode() not work with " - " character

问题描述

例如，我想对文本进行子字符串化. 你好吗?"通过使用此代码

I want to substring the text, ex. "Hello - How are you?" by using this code

$text= "Hello - How are you?";
$strings = explode(' - ',$text);
echo $strings[0]; // Hello
echo $strings[1]; // How are you

由于'-'，因此无法正常工作.

it will not work, because of ' - '.

如果我更改为:

$text= "Hello-How are you?";
$strings = explode('-',$text);
echo $strings[0]; // Hello
echo $strings[1]; // How are you

没关系.

有人可以帮助我吗?谢谢.

Can someone help me? Thank you.

推荐答案

我有一个相同的问题，经过一个小时的调查，结果发现从Microsoft Word复制的文本有这样的问题，word选择转换减号( -)到破折号(–)，在这里您可以并排查看它们的区别: -

I had the same problem, after an hour of investigating, turns out that texts copied from Microsoft Word have such a problem, word chooses to convert the minus character ( - ) to en dash ( – ) here you can see them side by side to see the difference: -–

我不知道单词为什么会这样，但是我们习惯于看到单词这样令人讨厌的事情，并且您永远不应该让任何人将单词从单词复制到您的应用程序中！

I don't know why word does that, but we are used to see such annoying things done by word and you should never let anyone copy a text from word to you application!

要使您的代码在以下条件下工作，必须首先替换以下奇数字符:

To make you code work in these conditions you must first replace these odd characters:

$text= "Hello-How are you?";
$strings = str_replace('–', '-', $text);
$strings = explode('-',$text);
echo $strings[0]; // Hello
echo $strings[1]; // How are you
