PHP regex help

[andytan91]

Hello guys i am trying regex this line string containing $parts = preg_split("/\.\(.*\)\.\(.*\)/", $file);

 

 

 

Currently this is what i've done. I would like to only regex the value in the .* placing so i am putting hi as a replacement. However, it doesnt work..i have tried this out for very long..i hope someone can guide me..thanks:)

$batch_contents = preg_replace('~\$parts = preg_split\(\"\/\\\.\\\((\.\*\\\)\\\)\\\.\\\((\.\*\\\)\\\)\/\", \$file\);~i' , '\$parts = preg_split\(\"\/\\\.\\\((hi\\\))\\\.\\\((hi\\\))\\\/\", \$file\);', $batch_contents);
