phpstudy does not support 64-bit php by default.

Memo:

It is easier to use phpstudy on windows, but all its default php versions are 32-bit , there are pitfalls, such as the maximum value of int.

So click to open the link http://windows.php.net/download#php-7.0-nts-VC14-x64 from the php official website, download a 64-bit php7 and throw it under the php directory of phpstudy ( The directory together with other versions);

After throwing it in, change the name to a shorter one, stop and restart phpstudy, the php version just thrown in will be automatically loaded, just switch it over.

I use nginx+php, other types such as APACHE, IIS, etc. have not been tried

Note: PHP official website pointed out that only Only 7 and above support 64-bit, the previous ones were all 32-bit

x86_64 Builds

The x64 builds of PHP 5 for Windows are experimental, and do not provide 64 -bit integer or large file support.

PHP 7 provides full 64-bit support. The x64 builds of PHP 7 support native 64-bit integers, LFS, 64-bit memory_limit and much more.
