Thank you for your bug report.
A workaround for what you want is adding 0:
php -r 'echo 0 + "5.6401418785e+05";'
564014.18785

> When an E notated integer
When an E notated float*
intval() on the string also (predictably) produces the same result as
casting to int

Description:
------------
When an E notated integer is in a string, and you try to cast it to an
integer, the value stops at anything non-integer, reducing the ability
to cast notated numbers. It does not first check or convert the value
to a float to account for E notation.
The documentation on type juggling doesn't mention this limitation, and
it is not the expected result.
Reproduce code:
---------------
$ php -r 'var_dump((int)"5.6401418785e+05");'
int(5)
$ php -r 'var_dump((int)5.6401418785e+05);'
int(564014)
$ php -r 'var_dump((int)(float)"5.6401418785e+05");'
int(564014)
