$txt=cctv1=3010汶上综合频道cctv17=3011汶上生活频道;使用php正则输出文字30103011

You can use the following PHP code to extract the desired text using regular expressions:

$txt = "'cctv1'=>['301',0],//汶上综合频道
'cctv17'=>['301',1],//汶上生活频道";

$pattern = "/\['(\d+)',(\d+)\]/";
preg_match_all($pattern, $txt, $matches);

print_r($matches[0]);

This code will output:

Array
(
    [0] => ['301',0]
    [1] => ['301',1]
)

Please note that the regular expression pattern assumes that the desired text is enclosed in square brackets with a single quote before the opening bracket. If the actual format of the text is different, you may need to modify the regular expression pattern accordingly.
