PHP uses the preg_split function to split strings containing newlines and semicolons

This article mainly introduces the use of preg_split function in PHP to split strings containing newlines and semicolons. It has certain reference value. Now I share it with you. Friends in need can refer to it

preg_ split() Function is used to split strings using regular expressions. Its main difference from the <span class="hljs-keyword" style="color:rgb(167,29,93);">split</span>() and explode() functions is:

<span class="hljs-keyword" style="color:rgb(167,29,93);">split</span>()Function: Use regular expressions to split the string and return an array, if an error occurs, <span class="hljs-literal" style="color:rgb(0,134,179);">false</span>.

preg_split() Function : Uses Perl-compatible regular expression syntax, usually faster than <span class="hljs-keyword" style="color:rgb(167,29,93);">split</span>() .

explode()Function: Use one string to split another string, usually faster than the above two functions.

<span class="hljs-attribute" style="color:rgb(0,134,179);">preg_</span> split() The syntax of the function is:

array preg_split( string pattern, string subject [, int limit [, int flags]] )

Parameter description:

这样，我们就有了按换行符和分号分割字符串的方法了。

$result = preg_split('/[;\r\n]+/s', $value);   // 返回数据保存在$result数组中

其中：

\r 表示：回车符(ACSII：13 或0x0d)，就是我们常说的硬回车。

\n 表示：换行(ACSII：10 或0x0a)，就是我们常说的软回车。

分号就不用说了吧：）
