我有以下表现: $exp = "/^(?!.*?that).*$/";
这是为了匹配不包含“”任何线。 我有以下三个句子: $str = array(
"I like this sentence.", #line1
"I like that sentence.", #line2
"I link THAT sentence." #line3
);
匹配是大小写
所以我想看看下面的文字: This is some header 1
nonsense text 1
Repeated item 1
Repeated item 1 Data
nonsense text 1
Repeated item 2
Repeated item 2 Data
This is some header 2
nonsense text 1
Rep
我正在为Drupal开发基于正则表达式的过滤器。这是正则表达式/[asciidoc]((.|\n)*)\[\/asciidoc]。当它在文本中出现多次时,[asciidoc]和[/ asciidoc]的所有实例都由第一个和最后一个匹配。 例如。在这样的代码 [asciidoc] here is some text to be filtered[/asciidoc]
a bit of text
