phptrace is a low-overhead tracing tool for PHP.

It can trace all PHP executing, function calls, request information during

run-time. And provides features like Filter, Statistics, Current Status and so

on.

It is very useful to locate blocking, heavy-load problems and debug in all

environments, especially in production environments.

Features:

* low-overhead, when extension loaded and trace is off

* stable, running on [Qihoo 360](http://www.360safe.com/) and tested on mainstream frameworks

* ease of use, view PHP run-time status without extension installation

Misc:

- [PECL Download](https://pecl.php.net/package/trace)

> News

> We have build another interesting project [pika](https://github.com/Qihoo360/pika).

> It's a NoSQL compatible with Redis protocol with huge storage space.

## Install from source

1. Extracting tarball

    ```

    tar -xf phptrace-{version}.tar.gz

    cd phptrace-{version}/extension

    ```

2. Build

    PHP Extension

    ```

    {php_bin_dir}/phpize

    ./configure --with-php-config={php_bin_dir}/php-config

    make

    ```

    CLI Binary

    ```

    make cli

    ```

3. Install & Configure

    Install PHP Extension, CLI Binary into PHP path

    ```

    make install-all

    ```

    Edit `php.ini`, add the following line. A reload is needed if PHP running

    on php-fpm mode.

    ```

    extension=trace.so

    ```

4. Verify

    ```

    php -r 'for ($i = 0; $i < 20; $i++) usleep(50000);' &

    phptrace -p $!

    ```

    You should see something below if it works fine

    ```

    process attached

    [pid 3600]> cli php -

    [pid 3600]> {main}() called at [Command line code:1]

    [pid 3600]    > usleep(50000) called at [Command line code:1]

    [pid 3600]    < usleep(50000) = NULL called at [Command line code:1] ~ 0.051s 0.051s

    [pid 3600]    > usleep(50000) called at [Command line code:1]

    [pid 3600]    < usleep(50000) = NULL called at [Command line code:1] ~ 0.051s 0.051s

    [pid 3600]    > usleep(50000) called at [Command line code:1]

    [pid 3600]    < usleep(50000) = NULL called at [Command line code:1] ~ 0.051s 0.051s

    [pid 3600]    > usleep(50000) called at [Command line code:1]

    ...

    ```

## Usage

Just try `php example.php`.

### Command line options

* trace     trace running php process(default)

* status    display php process status

* version   show version

* -p        specify php process id ('all' to trace all processes)

* -h        show helper

* -v        same as version

* -f        filter data by type(url,function,class) and content

* -l        limit output count

* --ptrace  in status mode fetch data using ptrace

### Trace executing

```

$ phptrace -p 3600

[pid 3600]    > Me->run() called at [example.php:57]

[pid 3600]        > Me->say("good night") called at [example.php:33]

[pid 3600]        < Me->say("good night") = NULL called at [example.php:33] ~ 0.000s 0.000s

[pid 3600]        > Me->sleep() called at [example.php:34]

[pid 3600]            > Me->say("sleeping...") called at [example.php:27]

[pid 3600]            < Me->say("sleeping...") = NULL called at [example.php:27] ~ 0.000s 0.000s

[pid 3600]            > sleep(2) called at [example.php:28]

[pid 3600]            < sleep(2) = 0 called at [example.php:28] ~ 2.000s 2.000s

[pid 3600]        < Me->sleep() = NULL called at [example.php:34] ~ 2.000s 0.000s

[pid 3600]        > Me->say("wake up") called at [example.php:35]

[pid 3600]        < Me->say("wake up") = NULL called at [example.php:35] ~ 0.000s 0.000s

[pid 3600]    < Me->run() = NULL called at [example.php:57] ~ 2.000s 0.000s

```

### Print current status

$ phptrace status -p 3600

------------------------------- Status --------------------------------

PHP Version:       7.0.16

```

### Tracing with filter of url/class/function

```

$ phptrace -p 3600 -f type=class,content=Me

[pid 3600]> Me->run() called at [example.php:57]

[pid 3600]> Me->say("good night") called at [example.php:33]

[pid 3600]< Me->say("good night") = NULL called at [example.php:33] ~ 0.000s 0.000s

[pid 3600]> Me->sleep() called at [example.php:34]

[pid 3600]> Me->say("sleeping...") called at [example.php:27]

[pid 3600]< Me->say("sleeping...") = NULL called at [example.php:27] ~ 0.000s 0.000s

[pid 3600]< Me->say("wake up") = NULL called at [example.php:35] ~ 0.000s 0.000s

[pid 3600]< Me->run() = NULL called at [example.php:57] ~ 2.001s 0.000s

```

### Limit frame/URL display times

$ phptrace -p 3600 -l 2

[pid 3600]    > Me->run() called at [example.php:57]
