Edit report at https://bugs.php.net/bug.php?id=79317&edit=1 ID: 79317 Updated by: cmb@php.net Reported by: j dot arnold at qaamgo dot com Summary: opcache and setlocale issue -Status: Re-Opened +Status: Closed Type: Bug Package: opcache Operating System: OpenSuse 15.1 PHP Version: 7.4.3 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: As of PHP 8.0.0, float to string conversion no longer depends on the locale[1], so this ticket is resolved.

However, I think this generally is a valid bug report, so I'm re-opening. ------------------------------------------------------------------------ [2020-02-28 13:40:34] j dot arnold at qaamgo dot com Thanks alot! Actually we missed the difference in optimization_level when comparing 7.3 with 7.4. ------------------------------------------------------------------------ [2020-02-28 13:19:10] cmb@php.net This is due to opcode optimization, in this case OPcache produces: ECHO string("Concatenated string: 0,5 invalidate cache for this class by changing something here: v1<br />") This also potentially happens with PHP 7.3; it depends on opcache.optimization_level. Using opcache.optimization_level=0x7FFEBF7F (i.e. disabling bit 7) makes the code working as expected. ------------------------------------------------------------------------ [2020-02-28 12:55:01] j dot arnold at qaamgo dot com > and how does that justify different behavior with or wuthout opcache? exactly, also with opcache the first call is float is correct with a "," and the second call is incorrect with a "." ------------------------------------------------------------------------ [2020-02-28 12:42:59] bugreports at gmail dot com > This is due to the fact that displaying floats are locale aware and how does that justify different behavior with or wuthout opcache? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
