Bug #71827 [NEW]: substr_replace bug when length type is string

From: php-mailing-list at lool dot fr Operating system: PHP version: 7.0.4 Package: Strings related Bug Type: Bug Bug description:substr_replace bug when length type is string Description: ------------ When running it under php 7, $line is unchanged and a message is emitted : PHP Warning: substr_replace(): 'from' and 'len' should be of same type - numerical or array in test.php on line 3. $len is not auto-casted in integer…. Btw the message is not very clear as it mentions from and len that are not within the doc. (in my real source code, $len was extracted as string from a database). When $len is an integer, the function works as expected. Tested ok on php 5.3.10 Tested Not ok on php 7.0.3 Best regards, Pascal KISSIAN Test script: --------------- test results on https://3v4l.org/svDrE <?php $line = str_repeat(' ',20); $value ='03'; $pos=0; $len='2'; $line = substr_replace($line,$value,$pos,$len); echo "[$line]\n"; ?> Expected result: ---------------- [03 ] Actual result: -------------- Warning: substr_replace(): 'from' and 'len' should be of same type - numerical or array in /in/svDrE on line 3 [ ] -- Edit bug report at https://bugs.php.net/bug.php?id=71827&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71827&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71827&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71827&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71827&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71827&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71827&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71827&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71827&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71827&r=support Expected behavior: https://bugs.php.net/fix.php?id=71827&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71827&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71827&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71827&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71827&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71827&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71827&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71827&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71827&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71827&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71827&r=mysqlcfg
