Related discussion for is_numeric_string:
http://markmail.org/message/ax2drcb6dolr5agl. General consensus is that we

| This is bugged also for hex numbers:
The results are as expected according to the documentation. Note,
that a hexadecimal number is only reported as being numeric, if it
is in hexadecimal string notation (i.e. starting with 0x). The first
example is correctly reported as being numeric, because the "e" is
recognized as starting the exponential part of the number.

This is bugged also for hex numbers:
print "526e948280122 " .(is_numeric("526e948280122") ? "numeric" : "not
numeric"). PHP_EOL;
print "526a948280122 ". (is_numeric("526a948280122") ? "numeric" : "not
numeric"). PHP_EOL;
print "0x526a948280122 ". (is_numeric("0x526a948280122") ? "numeric" : "not
numeric"). PHP_EOL;
print "526f948280122 ". (is_numeric("526f948280122") ? "numeric" : "not
numeric"). PHP_EOL;
output is:
526e948280122 numeric
526a948280122 not numeric
0x526a948280122 numeric
526f948280122 not numeric
tested with versions 5.5.4-1 and 5.4.4 (Debian version 5.4.4-14+deb7u5)

This problem was introduced when binary format integer was supported.
is_numeric()/intval() (many others) were not taken into account new format.
