$foo = (array) 'foo';
var_dump($foo);
A couple perfectly reasonable (though wrong) outputs:
#1
array (3){
0 => 'f',
1 => 'o',
2 => 'o'
);
And, actually, PHP having been derived (partially) from C, one could
almost argue this is the EXPECTED output. :-)
#2
array (1) {
'foo' => 'foo'
}
Which might work just fine for whatever the original code was doing,
but isn't quite the same as what happens...
#3
array (1) {
'foo' => TRUE
}
Bit of a stretch, I suppose...
#4
ERROR: Invalid typecast of String to Array.
Not very PHP, I suppose, but there it is...
