How to use it
build
You'll need to install the Boost library first.
macOS:
brew install boost
Ubuntu:

CentOS:
yum install boost boost-devel
phpize --clean && \
phpize && \
./configure && \
make clean && \
make && \
make install
set the ini file:
zend_extension=yasd
see the extension info:
php --ri yasd
IDE debug mode
zend_extension=yasd
yasd.debug_mode=remote
yasd.remote_host=127.0.0.1
yasd.remote_port=9000

set the ini file:
zend_extension=yasd
yasd.debug_mode=cmd
start debug
php -e test.php
list
l
list source code
breakpoint
b absolute-file-path lineno
This will also save the breakpoint information in the cache file -- .breakpoints_file.log
You can change this file name by the ini file, e.g.
yasd.breakpoints_file="yasd.log"
If the cache file exists, the breakpoints in the file are automatically loaded when debug is started.
Delete breakpoints
d number
If a breakpoint is set or deleted without specifying absolute-file-path
, It will set breakpoint in the current file.
watch point
We can monitor the variable changes or expression, for example:
watch $a
watch $a > 10
watch $name == 'swoole'
unwatch point
unwatch number
run
r
step over
n
step into
s
step out
f
backtrace
bt
info
show all breakpoints:
info breakpoints
show all watchpoints:
info watchpoints
continue
c
quit
q
p $a
p $this
p $this->prop

Q&A
Debugging with phpstorm (remote mode)
-
the port phpstorm listens on should be the one used for xdebug, also make sure remote connections are allowed:
-
do NOT forget to use
-e
option when running scripts, debugging will not work otherwise -
ensure that phpstorm listens on incoming connections:
Slow Start Framework
When using yasd
, if the framework starts slowly (most of the time it's because the framework is scanning a lot of files), you can execute the following command.
Hyperf
composer dump-autoload -o
Then modify the following configuration config/config.php
:
'scan_cacheable' => env('SCAN_CACHEABLE', true)

The breakpoint is not triggered
- No absolute path to the file is used
- The breakpoint is not a valid line, such as a function declaration, blank line, etc
- The code is generated with proxy classes, such as Hyperf. So you need to set breakpoints in the proxy class.
