Bug #76717 [NEW]: var_export() does not create a parsable value for PHP_INT_MIN

From: fredemmott Operating system: All PHP version: 7.3.0beta1 Package: Unknown/Other Function Bug Type: Bug Bug description:var_export() does not create a parsable value for PHP_INT_MIN Description: ------------ var_export() is documented as "Outputs or returns a parsable string representation of a variable" It generates an unparseable value for PHP_INT_MIN: it renders it as a negative decimal. -x is not a negative literal; it's a unary op on x. var_export generates '-9223372036854775808' - but as '9223372036854775808' is greater PHP_INT_MAX, this generates a float. Test script: --------------- <?php var_export(PHP_INT_MIN); echo "\n"; var_export(PHP_INT_MAX); echo "\n"; $min = eval('return '.var_export(PHP_INT_MIN, true).';'); $max = eval('return '.var_export(PHP_INT_MAX, true).';'); var_dump($min === PHP_INT_MIN); var_dump($max === PHP_INT_MAX); var_dump($min); var_dump($max); Expected result: ---------------- The last 4 lines of output should be true, true, (an int: value of PHP_INT_MIN), (an int: value of PHP_INT_MAX) Actual result: -------------- -9223372036854775808 9223372036854775807 bool(false) bool(true) float(-9.2233720368548E+18) int(9223372036854775807) -- Edit bug report at https://bugs.php.net/bug.php?id=76717&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76717&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76717&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76717&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76717&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76717&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76717&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76717&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76717&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76717&r=support Expected behavior: https://bugs.php.net/fix.php?id=76717&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76717&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76717&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76717&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76717&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76717&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76717&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76717&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76717&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76717&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76717&r=mysqlcfg
