本文实例讲述了PHP正则匹配反斜杠'\'和美元'$'的方法。分享给大家供大家参考,具体如下:
1. test.php:
1
2
3
4
5
6
7
8
9
10
11
12
|
<?php $content = '1111111<td>2222222<\/td>3$' ; //'\\\\\/' 第1个'\'转义字符串的第2个'\',字符串为'\' //第3个'\'转义第4个'\',相当于字符串'\' //第5个'\'转义第4个'/',相当于字符串'/' //字符合起来为'\\/' 两个'\\' 正则表达式看做'\' $pattern = '/<td>([0-9]{7,})<\\\\\/td>\d\\$$/' ; $result = preg_match_all( $pattern , $content , $match_result ); if ( $result ) print_r( $match_result ); else echo ( "not match" ); |
2. 方法二:
1
2
3
4
5
6
7
|
$content = '1111111<td>2222222<\/td>3$' ; $pattern = "!<td>(\d{7,})<\Q\/\Etd>\d\Q$\E!" ; $result = preg_match_all( $pattern , $content , $m ); if ( $result ) print_r( $m ); else echo ( "not match" ); |
3. 运行结果:
1
2
3
4
5
6
7
8
9
10
11
|
Array ( [0] => Array ( [0] => <td>2222222<\/td>3$ ) [1] => Array ( [0] => 2222222 ) ) |
希望本文所述对大家PHP程序设计有所帮助。
