在PHP中使用的正则表达式，用于从文本字符串中删除括号中的特定文本

Question

Can't figure this one out... I need a regular expression to use in PHP for removing particular text from a text string...

My text strings are like this: "The product we're talking about [Art.0430000] is a good product" "The product we're talking about [Art.0430001] is a good product" "The product we're talking about [Art.7852000] is a good product"

I need to remove [Art.0430000], [Art.0430001], [Art.7852000] from the strings...

Answer 1

The regular expression should be:

\[Art\.[0-9]+\]

(In words: The literal string "[Art.", followed by one or more numerals in the range 0-9, followed by the literal string "]".)

In PHP:

$pattern = '/\[Art\.[0-9]+\]/';
$result = preg_replace($pattern, "", $string);

Answer 2

我没有测试过，但是应该可以工作：

preg_replace_all("/\[Art(^\]+)\]/", "", $string);

Answer 3

If you also want to compress the white space left over (2 spaces to 1 space);

$pattern = '/\[Art\.[0-9]+\]\s*/';
$result = preg_replace($pattern, "", $string);

Answer 4

$pattern = "#\\[Art\\.([o-9])+\\]#"; str_replace($pattern,"",$str);
