Readme in Chinese 中文
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:
Misc:
News We have build another interesting project pika. It's a NoSQL compatible with Redis protocol with huge storage space.
Extracting tarball
tar -xf phptrace-{version}.tar.gz
cd phptrace-{version}/extension
Build
PHP Extension
{php_bin_dir}/phpize
./configure --with-php-config={php_bin_dir}/php-config
make
CLI Binary
make cli
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
Verify
php -r 'for ($i = 0; $i < 20; $i++) usleep(50000);' &
phptrace -p $!
You should see something below if it works fine
