How to validate PHP in VS code using WSL php

Question

In VS code you can validate php using php executable. But is there a way to use php installed on WSL instead?

Answer 1

What worked for me:

Create php.bat file:

@echo off
set v_params=%*
set v_params=%v_params:\=/%
set v_params=%v_params:c:=/mnt/c%
set v_params=%v_params:"=\"%
@bash -c "php %v_params%"

put it in C:\WSL-Tools\php.bat

Then, in VScode settings (Ctrl+comma):

"php.validate.executablePath": "C:\\WSL-Tools\\php.bat"

And it works.

Answer 2

The other answer did not work for me neither: after some work I came up with these two scripts:

This one is called php.bat and I placed it in C:\wsl-tools\:

@echo OFF
setlocal ENABLEDELAYEDEXPANSION
rem Collect the arguments and replace:
rem  '\' with '/'
rem  'c:' with 'mnt/c'
rem  '"' with '\"'
set v_params=%*
set v_params=%v_params:\=/%
set v_params=%v_params:C:=/mnt/c%
set v_params=%v_params%
set v_params=%v_params:"=\"%

rem Call the windows-php inside WSL.
rem windows-php is just a script which passes the arguments onto
rem the original php executable and converts its output from UNIX
rem syntax to Windows syntax.
C:\Windows\sysnative\bash.exe -l -c "windows-php %v_params%"

This one is called windows-php and is placed somewhere in the WSL path (i chose /usr/local/bin).

# Pass all the arguments to PHP.
output=$(php "$@")
# Perform UNIX->WINDOWS syntax replacements.
output="${output//$'\n'/$'\r'$'\n'}"
output="${output//\/mnt\/c/C:}"
output="${output//\//\\}"
# Echo corrected output.
echo $output

Setting "php.validate.executablePath": "c:\\wsl-tools\\php.bat" works for me.
