I have a text file, I am parsing it using a regex and saving in the table, is shows me Notice: Array to string conversion in /opt/lampp/htdocs/parsermine/index.php on

the regex is

preg_match_all('/([0-9]{1,3}.){3}[0-9]{1,3}/', $line, $matches); var_dump($matches[0]);

and dump is

array(1) { [0]=> string(11) "192.168.1.2" } 
array(1) { [0]=> string(11) "192.168.1.2" } 
array(1) { [0]=> string(11) "192.168.1.2" } 
array(1) { [0]=> string(11) "192.168.1.2" }

help me to sort out the problem

  • I didn't have that notice, I'm using PHP 7. Are you sure this is what triggered the notice, and why a notice should be a problem? just saying Commented Aug 25, 2017 at 5:47

    Which line of index.php does the error message point to? What is on that line? What is $line? Is it a string or an array? Commented Aug 25, 2017 at 6:04
  • I can't even replicate the problem. If $line is an array you get a fatal warning saying preg_match needs two strings one array is given. If the $line is a string then all works as it's supposed to. And I don't understand the dump. It returns four arrays like that. I can't make that happen either. There must be more code that is causing the problem that we don't see. Commented Aug 25, 2017 at 6:58
  • Actually I want to display the dump in a column of html table, and it displays the notice over there. <td><?php print $matches[0]" <br> "."\n";?></td> Commented Aug 25, 2017 at 7:04
