如何使用 "POSIX" 正则表达式替换正则表达式中的文本
How to replace text in regex by using "POSIX" regex
我有现有代码在 PCRE 方法中执行，我想在 POSIX 中具有相同的功能。
下面是我在 PCRE 中做的示例代码。
<?php
$regex = "/(\d)/";
$content = "In the garden have dog,cat,23242,rabbit.";
echo preg_replace($regex,"<span style='color:green'></span>",$content);
//Result:
//In the garden have dog,cat,<span style='color:green'>2</span><span style='color:green'>3</span><span style='color:green'>2</span><span style='color:green'>4</span><span style='color:green'>2</span>,rabbit.
我正在尝试在 POXIS 中做同样的事情，但无法获得相同的输出。
下面是我在 POSIX.;
中所做的示例代码
<?php
$regex = "([[:digit:]])";
$content = "In the garden have dog,cat,23242,rabbit."
echo ereg_replace($regex,"<span style='color:green'></span>",$content);
//Result:
//In the garden have dog,cat,<span style='color:green'></span><span style='color:green'></span><span style='color:green'></span><span style='color:green'></span><span style='color:green'></span>,rabbit.
请注意 ereg_replace,

如果您的 PHP 环境不支持 preg_replace，请在替换模式中使用带有 \1 而不是 </code> 的当前代码。</p>
<pre><code>$regex = "([[:digit:]]+)";
$content = "In the garden have dog,cat,23242,rabbit.";
echo ereg_replace($regex,"<span style='color:green'>\1</span>",$content);
// => In the garden have dog,cat,<span style='color:green'>23242</span>,rabbit.
