Try to store rand() into a int first. rand() can be double, and maybe explode allocated area of zend engine

int a = (int)rand();
if( a % 2 == 0 ) {
   return "string";
}
else {
   return 123;
}

I think you compile php-cpp with one version of php, and update php.

Try compile php-cpp again with this version of PHP. Make sure dev package are the same of binary.

Post compile output if you still have problem

I removed remi version,and built from source,nothing help. main.zip here is all my code.

scorninpc commented 5 years ago

Works fine. Today I upgrade to 7.3.6, but worked with 7.3.5 too

Seleção_110

ps: stdlib and std namespace are unuseful for your code

I dont know. I got segment fault when i try to clean memory, and PHP try to clear after again. But u dont do it anywere. I really don't know.

My last shot, are you try run a vbox with clean install to see if any of your machine are broken.

lifenglsf commented 5 years ago

Already in vmbox，I try new one.I confused too

image minmal centos7.6，everything not change Thanks，anyway

scorninpc commented 5 years ago

Try to do hard debug if you dont know how to dbg:

1º - Run php file, only with some echo, not calling your functions, but with extension loaded if OK: 2º - Run php file, only with myFunction(), without showing result with var_dump if OK: 3º - Run php file, only with myFunction2(), without showing result with var_dump if OK: 4º - Run php file, only with sum_everything, without showing result with var_dump ...

Can you show this test for us?

lifenglsf commented 5 years ago

1.ok 2.segmentation fault 3.ok 4.ok The segmentation fault will only occur if myfunction is called.

scorninpc commented 5 years ago

Crash with myFunction() ? the simplest method?

Try replace Php::out to Php::call, to see if the problem is out put ou the method out()

Php::call("var_dump", "example output");
lifenglsf commented 5 years ago

Php::call works fine.

Crash with myFunction() ? the simplest method? Yes!

scorninpc commented 5 years ago

So try diferent methods of outputs

http://www.php-cpp.com/documentation/output-and-errors

Maybe some lib free buffer, and when PHP try free, this crash. Try use Php:echo or Php::call until you not find the wrong lib

lifenglsf commented 5 years ago

php::call works find only
