Intval() and the binary integer in a string 0b11101 is the binary integer in #PHP code. When the same value is in a string, dynamically acquired if you will, it cannot be cast to integer directly. This is where intval() saves the day. #phptip #phptrick

@AkubueAlexander One of the neat feature of ??= is that it skips entirely the call to the method when the value exists. You can use it as a failsafe, and when it is always defined, it is zero-cost. https://t.co/1WiiYW3FaX #phptip #phptrick

Sometimes, preg_match() is missing some subpatterns. This is a classic and puzzling bug in #PHP, with documented explanations. #phptip #phptrick

Today, I got bitten by someone who wrote “as” in uppercase AS and it made me use #PHP strripos() for the first time ever. Did you know there are 4 strpos() you can rely on? Also, don't use AS with constants, just because const should be uppercase! #phptip #phptrick

@brendt_gd He is fighting the classic bug of the 'trailing unmatched subpattern': #PHP skips the last subpatterns without match. To apply the final list() = array() without error, he then needs a default value, hence the + [null] #phptip #phptrick https://t.co/qdN9xjlezz

@PovilasKorop That is a great #phptip #phptrick, worth reminding on a regular basis. Note that it works on any #PHP number formats 0b111_111_1111, hexa, octal, etc. It doesn't work inside strings, so you need.... 🥁🥁🥁 eval()! or strtr()-like. https://t.co/FNQmNqDz51

Sometimes, null is an actual argument in #PHP native functions, and it is not obvious what features it unleashes. #phptrick #phptip https://t.co/NUwt93FrR2

$_FILES['avatar']['type'] in #PHP is a string the attacker typed. 🔐 main/rfc1867.c reads the Content-Type header of the multipart part, cuts it at the first ";" and hands it to you. No sniffing. No validation. NOTHING reads the bytes on disk. curl -F "avatar=@shell.php;type=image/png" and your check sees image/png. finfo_file() on tmp_name is the one that actually opens the file.

TIL that JSON tolerates duplicate keys. #PHP does not: it may only keep the last one, or throw an exception as error. #phptip #phptrick https://t.co/lMRoo6FjAE

#PHP 8.4 introduced array_find() to look for a value in an array, and also, its cousin, array_find_key(), which returns the key where to find that value. The second got less attention, but is arguably more useful. #phptip #phptrick https://t.co/zxv0pHYb11

So, it seems that it is possible to paint oneself in a corner and write an unreachable method. How would you call A::foo() in this code below? Come on, #PHP, there must be something here. #phptip #phptrick https://t.co/rsIs4gs8Ef

object is a type for arguments, but not for instanceof. This leads to strange results. And may be a PR. #phptip #Phptrick https://t.co/SQR6z3SaBv

Passing array by value, and updating its elements. Nothing new, it is the readonly and array_fill() syndrom for arrays. Better know about it. #phptip #phptrick https://t.co/7MSG3Go4j5
