本文操作环境:windows10系统、php 7.3、thinkpad t480电脑。

在php中如果我们要去掉字符串中所有的空格,最快捷有效的方式就是使用正则表达式。下面我们就来一起看下。

preg_replace 函数执行一个正则表达式的搜索和替换。

举个小例子:

<?php
$string = &#39;google 123, 456&#39;;
$pattern = &#39;/(\w+) (\d+), (\d+)/i&#39;;
$replacement = &#39;phpphp ${2},$3&#39;;
echo preg_replace($pattern, $replacement, $string);
?>
Copy after login

运行结果:

phpphp 123,456
Copy after login

下面我们使用正则匹配去除所有的空格

preg_replace(&#39;# #&#39;,&#39;&#39;,$goodid)
Copy after login
