30Installation
31============
32
33To install **phpdbg**, you must compile the source against your PHP installation sources, and enable the SAPI with the configure command.
34
35```
36cd /usr/src/php-src/sapi
37git clone https://github.com/krakjoe/phpdbg
38cd ../
39./buildconf --force
40./configure --enable-phpdbg
41make -j8
42make install-phpdbg
43```
44
45Where the source directory has been used previously to build PHP, there exists a file named *config.nice* which can be used to invoke configure with the same
46parameters as were used by the last execution of *configure*.
47
48**Note:** PHP must be configured with the switch --with-readline for phpdbg to support history, autocompletion, tab-listing etc.
49
50Command Line Options
51====================
52
53The following switches are implemented (just like cli SAPI):
54
55 - -n ignore php ini
56 - -c search for php ini in path
57 - -z load zend extension
58 - -d define php ini entry
59
60The following switches change the default behaviour of phpdbg:
61
62 - -v disables quietness
63 - -s enabled stepping
64 - -e sets execution context
65 - -b boring - disables use of colour on the console
66 - -I ignore .phpdbginit (default init file)
67 - -i override .phpgdbinit location (implies -I)
68 - -O set oplog output file
69 - -q do not print banner on startup
70 - -r jump straight to run
71 - -E enable step through eval()
72 - -l listen ports for remote mode
73 - -a listen address for remote mode
74 - -S override SAPI name
75
76**Note:** Passing -rr will cause phpdbg to quit after execution, rather than returning to the console.
