Instructions:
- Download the APD debugger
- untar it
- run 'phpize' in the directory
- ./configure
- make install (and with any luck it will install the php_apd.so module into your php modules directory.)
- edit the php.ini file and add the line (you need the full path)
zend_extension_debug=/usr/lib/php/2001...../php_apd.so
- try out this little test program:
#!/usr/bin/php -q
<?
apd_set_session_trace_socket("localhost", APD_AF_INET, 7777, 35);
apd_breakpoint(9);
for ($i=0;$i<10;$i++) {
echo "TEXT\n";
}
?>
- get hold of tcplisten
(it's a socket listening program on linux - kind of like a reverse version of telnet)
bash#tcplisten localhost 7777
- now run the file like this (you need the -e for the breakpoints to work!)
bash#/usr/bin/php -e
test.php
- the
program will start up and hang, meanwhile in the tcplisten window you
will see this. (the bold stuff is an example of what you can type in...
