Recursive PHP Lint script

phplint.sh

#!/bin/bash

for file in `find .`
do
    EXTENSION="${file##*.}"

    if [ "$EXTENSION" == "php" ] || [ "$EXTENSION" == "phtml" ]
    then
        RESULTS=`php -l $file`

        if [ "$RESULTS" != "No syntax errors detected in $file" ]
        then
            echo $RESULTS
        fi
    fi
done

Something like this would be pretty useful as a GitHub Action, I reckon.

I combined and added some parts:

1. @judgej redirect to /dev/null
2. Add -false after -prune to omit the vendor folder from output
3. Add $(nproc) to get the actual amount of usable cores

find . -path ./vendor -prune -false -o -type f -name '*.php' -print0 | xargs -0 -n1 -P$(nproc) php -l -n > /dev/null

Edit: Portable version with comment from @CodeBrauer:

find . -path ./vendor -prune -false -o -type f -name '*.php' -print0 | xargs -0 -n1 -P$(nproc 2> /dev/null || sysctl -n hw.ncpu) php -l -n > /dev/null

I ❤️ this discussion! You people are awesome!

3. Add $(nproc) to get the actual amount of usable cores

For those using macOS - nproc is not available, but you can use sysctl -n hw.ncpu

still havent found a good (portable) version for this
redirecting the output of php -l to /dev/null also hides the parse/syntax error messages

#!/bin/sh
set -ex

find . -type f -name '*.php' ! -path './vendor/*' -exec php -l -n {} \; | (! grep -v "No syntax errors detected" )
echo 'syntax OK'

This works fine on ubuntu, but on macOS it stops the script
