Question

我如何分隔文本例如

$text  = 'TEXT 1: Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.  TEXT 2:  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.'

现在，如果您注意到我有TEXT 1：...和TEXT 2：...在变量$ text。

我如何限制从TEXT 1（使用str TEXT 1 :)到TEXT 2（不使用str TEXT 2）显示此文本。我怎样才能显示从TEXT 2到文本结尾的文本？

Answer 1

您还可以使用preg_split：

print_r(preg_split('/TEXT \d:/', $text, NULL, PREG_SPLIT_NO_EMPTY));

输出：

Answer 2

您可以使用substr和strpos来完成此操作，

$text  = "TEXT 1: Lorem Ipsum is simply dummy text of the printing and 
typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.  TEXT 2:  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.";

echo substr($text, strpos($text, 'TEXT 1: ') + 8, strpos($text, 'TEXT 2: ') - 8);

Answer 3

这是一个可以做你想做的正则表达式。

$regex = '#TEXT 1: (?<text>.+) TEXT 2#';
$text = "TEXT 1: Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.  TEXT 2:  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.";

preg_match($regex, $text, $match);

echo $match['text'];

说明： #是分隔符然后它查找文本1，然后我们启动一个名为text的命名捕获组捕获组捕获每个角色，直到它击中TEXT 2。您可以使用$match['text']
