如何跟踪运行中的PHP进程对象数量？

写了一个脚本用来处理php内存泄漏问题(Linux Support Only):

wget http://gitlab.qima-inc.com/chuxiaofeng/zan-dev-doc/raw/master/zobjdump.sh
chown +x zobjdump.sh
sudo ./zobjdump.sh [pid]

#instances   #class

注意环境依赖

env_check()
{
    command -v php >/dev/null 2>&1 || { echo >&2 "php required"; exit 1; }
    command -v python >/dev/null 2>&1 || { echo >&2 "python required"; exit 1; }
    command -v gdb >/dev/null 2>&1 || { echo >&2 "gdb required"; exit 1; }
    if [[ $EUID -ne 0 ]]; then
        echo >&2 "root required"
        exit 1
    fi
    if [[ $(rpm -qa|grep '.*php.*debuginfo.*'|wc -l) == 0 ]]; then
        echo >&2 "php debuginfo required"
        exit 1
    fi
}
