Hard crash in PHP 7.4

[bobrundle]

Validating any email address in PHP 7.4 raises exception "Trying to access array offset on value of type null" in Parser.php at line 147

    if ($previous['type'] === EmailLexer::S_BACKSLASH

This is result of $previous being null for first character in string and new PHP 7.4 behavior "Trying to use values of type null, bool, int, float or resource as an array (such as $null["key"]) will now generate a notice"

Fix is to check for null...

    if ($previous != null && $previous['type'] === EmailLexer::S_BACKSLASH

This is what you want to write. Watch the format!! if ($previous != null && $previous['type'] === EmailLexer::S_BACKSLASH
