How to solve the problem that PHP does not generate core files when executing shell scripts

How does PHP solve the problem of not generating core files when executing shell scripts? Today I will bring you a method to solve the problem that PHP does not generate core files when executing shell scripts and running programs. Share it with everyone and give it as a reference. I hope to be helpful.

It is found that the core file is never generated, but when the script is manually run, the core file will be generated.

After guidance from a friend, it turned out that the problem was caused by the script execution environment:

Add ulimit -a >> 1.log to the script

Print as follows:

core file size     (blocks, -c) 0
data seg size      (kbytes, -d) unlimited
scheduling priority       (-e) 0
file size        (blocks, -f) unlimited
pending signals         (-i) 127364
max locked memory    (kbytes, -l) 64
max memory size     (kbytes, -m) unlimited
open files           (-n) 4096
pipe size      (512 bytes, -p) 8
POSIX message queues   (bytes, -q) 819200
real-time priority       (-r) 0
stack size       (kbytes, -s) 10240
cpu time        (seconds, -t) unlimited
max user processes       (-u) 127364
virtual memory     (kbytes, -v) unlimited
file locks           (-x) unlimited

core file size is actually 0

Add a sentence before the script runs the program: ulimit -c unlimited

To solve the problem, the core file can be generated.
