Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php filter_var's FILTER_VALIDATE_INT always casts its argument to a string before conversion, and exponents and decimal points are never accepted, this is no exception.

Test script: --------------- <?php ini_set('precision', 14); // PHP default $i = 12345678912345; // strlen($i) == 14 var_dump(strlen($i)); var_dump(filter_var((float) $i, FILTER_VALIDATE_INT)); // $i var_dump((float) $i == $i); // true $i = 123456789123456; // strlen($i) = 15 var_dump(strlen($i)); var_dump(filter_var((float) $i, FILTER_VALIDATE_INT)); // false instead of $i var_dump((float) $i == $i); // true Expected result: ---------------- int(14) int(12345678912345) bool(true) int(15) bool(123456789123456) bool(true) Actual result: -------------- int(14) int(12345678912345) bool(true) int(15) bool(false) bool(true) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68551&edit=1
