I don't know, it's just simple script

phloc.sh

#!/bin/bash
# Script name: phloc
# Usage:
#   phloc [port] [doc_root]
#   port: port number to listen on (default: 8080)
#   doc_root: document root (default: current directory)
# Description:
#   Starts a PHP server on the specified port and document root.
#   If no port is specified, the default port 8080 is used.
#   If no document root is specified, the current directory is used.
#   The script is intended to be used for local development.
if [ $# -eq 0 ]; then
  port=8080
else
  port=$1
fi

doc_root="."

if [ $# -eq 2 ]; then
  doc_root=$2
fi

while true; do
  echo "Starting PHP server on port $port with document root $doc_root..."
  php -S 0.0.0.0:$port -t $doc_root

  # Check if the port is already in use
  if [ $? -eq 0 ]; then
    break
  else
    # Increment the port number and try again
    echo "Port $port is already in use, trying port $((port+1))..."
    port=$((port+1))
  fi
done
