Question

我正在尝试替换此字符http://www.fileformat.info/info/unicode/char/2014/index.htm 有一个常规冲刺，这是我现在似乎无法让它工作？

$dataold = "9am – 5pm"; // from a ms word doc

$data = mb_ereg_replace("[\xE2 \x80 \x94]", " - ", $dataold);

print_r($data);

Answer 1

为什么要使用八进制unicode格式呢？为什么不......

替换N-Dash

$dataold = "9am – 5pm"; // from a ms word doc
$data = mb_ereg_replace(" – ", " - ", $dataold);
print_r($data);

替换M-Dash

$dataold = "9am — 5pm"; // from a ms word doc
$data = mb_ereg_replace(" — ", " - ", $dataold);
print_r($data);

您的原始代码工作正常，但示例文本字符串有一个N-dash并且您正在测试M-dash。（并且您的RegEx中有额外的空格）。试试这个......

$dataold = "9am — 5pm"; // from a ms word doc
$data = mb_ereg_replace("[\xE2\x80\x94]", " - ", $dataold);
print_r($data);

Answer 2

试试这个：

$dataold = "9am – 5pm"; // from a ms word doc
$data = mb_ereg_replace("/ \\x{2014} /u", " - ", $dataold);
print_r($data);

Answer 3

我让它工作但是 - 直接从您粘贴的页面复制字符（从您的代码复制不起作用）。

<?php
$dataold = "9am — 5pm"; // from a ms word doc
$data = mb_ereg_replace("\x{2014}", "dash", $dataold);
print_r($data); // output = 9am dash 5pm
