docker run -it  dalongrong/phpspy   ./phpspy/phpspy --help

Usage:

phpspy [options] -P <pgrep-args>

phpspy [options] [--] <cmd>

Options:

-h, --help                         Show this help

-p, --pid=<pid>                    Trace PHP process at `pid`

-P, --pgrep=<args>                 Concurrently trace processes that

match pgrep `args` (see also `-T`)

-T, --threads=<num>                Set number of threads to use with `-P`

(default: 16)

-s, --sleep-ns=<ns>                Sleep `ns` nanoseconds between traces

(see also `-H`) (default: 10101010)

-H, --rate-hz=<hz>                 Trace `hz` times per second

(see also `-s`) (default: 99)

-V, --php-version=<ver>            Set PHP version

(default: auto;

supported: 70 71 72 73 74 80)

-l, --limit=<num>                  Limit total number of traces to capture

(approximate limit in pgrep mode)

(default: 0; 0=unlimited)

-i, --time-limit-ms=<ms>           Stop tracing after `ms` milliseconds

(second granularity in pgrep mode)

(default: 0; 0=unlimited)

-n, --max-depth=<max>              Set max stack trace depth

(default: -1; -1=unlimited)

-r, --request-info=<opts>          Set request info parts to capture

(q=query c=cookie u=uri p=path

capital=negation)

(default: QCUP; none)

-m, --memory-usage                 Capture peak and current memory usage

with each trace (requires target PHP

process to have debug symbols)

-o, --output=<path>                Write phpspy output to `path`

(default: -; -=stdout)

-O, --child-stdout=<path>          Write child stdout to `path`

(default: phpspy.%d.out)

-E, --child-stderr=<path>          Write child stderr to `path`

(default: phpspy.%d.err)

(default: 0; 0=find dynamically)

-a, --addr-sapi-globals=<hex>      Set address of sapi_globals in hex

(default: 0; 0=find dynamically)

-1, --single-line                  Output in single-line mode

-b, --buffer-size=<size>           Set output buffer size to `size`.

Note: In `-P` mode, setting this

above PIPE_BUF (4096) may lead to

interlaced writes across threads.

(default: 4096)

-f, --filter=<regex>               Filter output by POSIX regex

(default: none)

-F, --filter-negate=<regex>        Same as `-f` except negated

-d, --verbose-fields=<opts>        Set verbose output fields

(p=pid t=timestamp

capital=negation)

(default: PT; none)

-c, --continue-on-error            Attempt to continue tracing after

encountering an error

-#, --comment=<any>                Ignored; intended for self-documenting

commands

-@, --nothing                      Ignored

-v, --version                      Print phpspy version and exit

Experimental options:

-j, --event-handler=<handler>      Set event handler (fout, callgrind)

(default: fout)

-S, --pause-process                Pause process while reading stacktrace

(unsafe for production!)

-e, --peek-var=<varspec>           Peek at the contents of the var located

at `varspec`, which has the format:

<varname>@<path>:<start>-<end>

-g, --peek-global=<glospec>        Peek at the contents of a global var

located at `glospec`, which has

the format: <global>.<key>

where <global> is one of:

post|get|cookie|server|files|globals
