SAST
In order to save time for security practitioners, Static Application Security Testing tool was written. You can use the following code to analyze all regular expressions from your project:
grep -iorP "reg_\w+\s*\((\s*['\"](.*?)['\"])," * > regexp.txt && php index.php --file="./regexp.txt"
SAST can be downloaded from here:
