This is expected, PHP converts numerical string to type integer/float.
var_dump((int) "12345678901234567890123456789012");
var_dump((int) "12345678901234567890123456789011");
int(2147483647)
int(2147483647)

Description:
------------
If two strings containing numbers are compared using an if statement,
only the first 16 bytes of the string are compared. Any bytes after the
16th byte are ignored in the comparison.
Reproduce code:
---------------
<?PHP
$value1="12345678901234567890123456789012";
$value2="12345678901234567890123456789011";
if ($value1!=$value2){print"Not equal.<br>";}
if ($value1==$value2){print"Equal.<br>";}
var_dump($value1);
print "<br>";
var_dump($value2);
print "<br>";
?>
Expected result:
----------------
Not equal.
string(32) "12345678901234567890123456789012"
string(32) "12345678901234567890123456789011"
Actual result:
--------------
Equal.
string(32) "12345678901234567890123456789012"
string(32) "12345678901234567890123456789011"
