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.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AMDependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
