Edit report at https://bugs.php.net/bug.php?id=61549&edit=1 ID: 61549 Updated by: dmitry@php.net Reported by: tstarling@php.net Summary: 2GB string size limit is too small -Status: Re-Opened +Status: Closed Type: Feature/Change Request Package: Scripting Engine problem Operating System: any PHP Version: master Assigned To: dmitry Block user comment: N Private report: N New Comment: Implemented in PHP-7 (only in 64-bit version of course). Previous Comments: ------------------------------------------------------------------------ [2012-03-31 11:57:21] tstarling@php.net It's not quite as simple as changing the type of zvalue_value.str.len. String sizes are assumed to be ints or unsigned ints in lots of other interfaces, perhaps most notably zend_parse_parameters(). ------------------------------------------------------------------------ [2012-03-31 01:46:13] yohgaki@php.net I think this is good changes for next PHP release. ------------------------------------------------------------------------ [2012-03-31 01:45:20] yohgaki@php.net Re-opened as feature request. String size is limited by zvalue due to "signed int" for string length. 2GB string size limit is too small for today. Memory is cheap and there many PC has more than 8GB or more. It's simply too small for load large files, etc. ------------------------------------------------------------------------ [2012-03-30 10:26:27] yohgaki@php.net This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. ------------------------------------------------------------------------ [2012-03-29 03:08:53] tstarling@php.net Description: ------------ According to language.types.string.php: "Note: It is no problem for a string to become very large. PHP imposes no boundary on the size of a string; the only limit is the available memory of the computer on which PHP is running." The incorrectness of this statement is growing as time goes on. Strings are limited to 2GB, which is a small and ever-shrinking fraction of the memory available on a typical modern server. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61549&edit=1
