10 GIG txt file - Need to delete info on every line

[bigjayin20]

example: xxxxx eqweqwe www.google.com xxxxx qweqweqweqw

I need to delete the xxxxx eqweqwe data on every line and only end up with www.google.com is there anyone that can guide me for $ ?

// Extract URLs using regex $pattern = '/www\.[^\s]+/'; $urls = [];

I also agree with Ragnar28 that the best way to solve this issue is to use RegEx, but you might also consider using e.g. file and
array_map.
.

e.g [ on-line ]

10gig-test.txt

xxxxx eqweqwe www.google.com xxxxx qweqweqweqw
xxxxxxx eqweqweaaaaa www.lorem.com/lorem/ xxxxxxx qweqweqweqw
xxxxx eqweqwe www.lorem.ipsum.com/index?l=lorem yyyyyyy qweqweqweqw
xxxxx eqweqwe www.google.com xxxxx qweqweqweqw

xxxxx eqweqwe www.google.com xxxxx qweqweqweqw


xxxxx eqweqwe www.ipsum.com xxxxx qweqweqweqw
xxxxx eqweqwe www.ipsum.com/lorem-lorem-ipsum xxxxx yyyyyyyyy qweqweqweqw

    $file = file('10gig-test.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
    $file = array_map(function($line) { return explode(' ', substr($line, strpos($line, 'www')))[0] . PHP_EOL; }, $file);
    file_put_contents('10gig-test_clean.txt',  $file);

    // only for demonstration purpose
    var_dump(array_map(function($line) { return trim($line, PHP_EOL); }, $file));
