Assuming this is a linux server and you have cronjobs available

///Check for running script and run if non-exist///

#! /bin/bash

check=$(ps -fea | grep -v grep | grep script.php | wc -l)
date=$(date +%Y-%m%d" "%H:%M:%S)
if [ "$check" -lt 1 ]; then
echo "["$date"] Starting script" >> /path/to/script/log/
/sbin/script  ///Call the script here - see below///
fi

script file

#/usr/bin/php /path/to/your/php/script.php
