phpDocumentor - Could not open input file: phpdoc.php

Run:

pear

it will set %PHP_PEAR_PHP_BIN% for you.

You will need to set the environmental path for "PHP_PEAR_BIN_DIR" to the directory where "phpdoc.php" is.

I have changed phpdoc.bat file to point to exactly location of phpdoc.php

@echo off
if "%PHPBIN%" == "" set PHPBIN=php.exe
if not exist "%PHPBIN%" if "%PHP_PEAR_PHP_BIN%" neq "" goto USE_PEAR_PATH
GOTO RUN
:USE_PEAR_PATH
set PHPBIN=%PHP_PEAR_PHP_BIN%
:RUN
"%PHPBIN%" "C:\wamp\bin\php\php5.3.10\phpdoc.php" %*

On my windows 7 system, I have my set up phpDocumentor (version 2.6.1) in wamp and my paths are like:

D:\Projects\wamp\www\phpDocumentor
D:\Projects\wamp\www\phpDocumentor\bin 

Now what I did is I edited the phpdoc.bat file located at path:

D:\Projects\wamp\www\phpDocumentor\bin\phpdoc.bat

It contained code as shown below:

@echo off
if "%PHPBIN%" == "" set PHPBIN=php.exe
if not exist "%PHPBIN%" if "%PHP_PEAR_PHP_BIN%" neq "" goto USE_PEAR_PATH
GOTO RUN
:USE_PEAR_PATH
set PHPBIN=%PHP_PEAR_PHP_BIN%
:RUN
"%PHPBIN%" "D:\Projects\wamp\www\phpDocumentor\bin\phpdoc" %*

So, I edited the last line "%PHPBIN%" "%PHP_PEAR_BIN_DIR%\phpdoc" %* with new code "%PHPBIN%" "phpdoc" %*. After phpdoc.bat looked like :

@echo off
if "%PHPBIN%" == "" set PHPBIN=php.exe
if not exist "%PHPBIN%" if "%PHP_PEAR_PHP_BIN%" neq "" goto USE_PEAR_PATH
GOTO RUN
:USE_PEAR_PATH
set PHPBIN=%PHP_PEAR_PHP_BIN%
:RUN
"%PHPBIN%" "phpdoc" %*

Thereafter I again ran the below command in cmd:

D:\Projects\wamp\www\phpDocumentor\bin>phpdoc

And the output was like:

D:\Projects\wamp\www\phpDocumentor\bin>phpdoc

Collecting files .. OK

D:\Projects\wamp\www\phpDocumentor\bin>

So, the output showed that it worked successfully !!

PHP's include_path will need the path to the directory that contains that phpdoc.php file. Otherwise, none of the phpDocumentor code that uses require/include statements with relative paths will be able to find anything.

I just encountered this on Windows 7 having installed phpDocumentor2 via PEAR. I found that running:

phpdoc -d . -t docs

in an elevated command prompt did the trick - I suspect there's still some PATH issue on my machine that makes that the case, but having done all the default install steps for both PEAR and phpDocumentor it has proven the quickest workaround I've found.

I've got the same error message, the already made answers brought me to the right path.

As I don't use wamp/xampp or any of these programms, I thought: why don't run it directly with PHP?

I had already installed PHP7.0.x globally through WebPI.

Only php needs to be prefixed to the command, everything worked:

php .\phpDocumentor\bin\phpdoc -d .\src\ -t .\dst\
