I read somewhere (and now I’m not finding where) that in php version 7 there is no memory lilmite. That is, the memory that can be allocated would be the machine’s RAM. Does it proceed? Has anyone read anything about it?

According to the manual:

memory_limit integer

Sets the maximum amount of memory in bytes a script is allowed to allocate. This helps prevent scripts badly written consume all available memory on the server. Note that to have no memory limit, set this directive to -1.

http://php.net/manual/en/ini.core.php#ini.memory-limit

I have already noticed that in previous versions, PHP limited the memory in 4GB, so the most that could reach was 4GB - 1MB:

ini_set('memory_limit', '4095M');

  • That, I was worried about a php7 script stealing all the server memory and harming other projects.
