Also note that $a is never declared, and starts with a value of NULL. By assigning a value with square brackets $a[]=, you're implicitly casting NULL to an empty array, and then appending a value.

Didn't know that $a[] = x adds an element to an array in PHP. I would classify that as a bizarre quirk since I don't know of any other language that does that.

while($a.=1); indefinetely adds characters to a string.

You can chop a byte with while($a.=1); -- just build a huge string versus a huge array.

@tbodt $a[]=1 evaluates to something truthy so the while() loop equates to while(true) and just keeps looping and adding elements to the $a array. Not sure if this can be classified as a quirk though. Is identifying a quirk a requirement of your question? Would you like me to deconstruct my answer into multiple lines?
