Regex PHP problems

Question

I am trying to get some information from a web page and I am using regex for such.

I’m using regex101.com to test the Pattern and I managed to reach one that suits me perfectly. It turns out that this Pattern works perfectly in regex101.com, but when I do the same thing in PHP, it doesn’t give any match.

This is my code in regex101.com: https://regex101.com/r/zgZL8W/2

Note that 7 occurrences are found.

This is my PHP code. Although using the same text and the same Pattern, no match is made.

$pattern = '/<span\>([0-9\/]{10})( {0,})+([A-zÁ-ÿ ]+) {1,}(&#[0-9]{1,6})*[; ]*([0-9]{2}\:{0,}[0-9]{0,2}) +[A-Z]+ +([A-z]{2,}-{0,}[A-z]*)<br \/> <\/span>([0-9]{1,2}). +([0-9]{1,5}) {0,}[0-9]{1,2} [ A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) +[0-9]{1,2} +[A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) +[0-9]{1,2} +[A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) +[0-9]{1,2} +[A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) +[0-9]{1,2} +[A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) {1,}[0-9]{1,2} +[A-zÁ-ÿ]{4,9}<br \/> ([0-9]{1,2}). +([0-9]{1,5}) +[0-9]{1,2} +[A-zÁ-ÿ]{4,9}</';

$mirror = file_get_contents('http://resultadodojogodobicho.deunopostehoje.com/sao-paulo/');

$data = [];

preg_match_all($pattern, $mirror, $data, PREG_SET_ORDER, 0);

var_dump($data);

Does anyone know what might be going on?

Answer 1

There are two errors in your Pattern that when passing to PHP can cause this error. The first one is very simple.

    • Your PHP code is being handled with formatting ASCII, and its text has special characters such as Á, É, etc. and needs to be treated as UTF-8. In order for the compiler to fix this error, you will need to add the flag /u in his regex.

    • The other error is also just a lack of attention. To separate the white characters from your Pattern, you used a space: . Which can cause the compiler to not identify them correctly depending on the version of your PHP. This error can be solved with the terms: \s or \h.
NOTE: Do not use \s in that case! The term may give match in all types of white characters, including line breaks (\n)! Use \h to give match in all space characters horizontal.

New regex:

/<span\>([0-9\/]{10})(\h{0,})+([A-zÁ-ÿ\h]+)\h{1,}(&#[0-9]{1,6})*[;\h]*([0-9]{2}\:{0,}[0-9]{0,2})\h+[A-Z]+\h+([A-z]{2,}-{0,}[A-z]*)<br\h\/>\h<\/span>([0-9]{1,2}).\h+([0-9]{1,5})\h{0,}[0-9]{1,2}\h[\hA-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h+[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h+[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h+[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h+[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h{1,}[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}<br\h\/>\h([0-9]{1,2}).\h+([0-9]{1,5})\h+[0-9]{1,2}\h+[A-zÁ-ÿ]{4,9}</u
