// Core extraction pattern
/([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}):([^:\s\n]+)/g
// Example matches:
john.doe@example.com:password123
user@gmail.com:pass456
admin@company.co.uk:securePass789
// For files >500MB, automatic server-side streaming:
while (($line = fgets($handle)) !== false) {
if (preg_match($pattern, $line, $matches)) {
// Process line by line - minimal memory usage
}
}
