前两天我正好也有这个需求，供参考。

```
<?php
echo "run";
exit(1); //用 exit 返回状态

?>
```

windows

```
@echo off
cls
:start
php index.php
if %errorlevel%==1 goto exceptionEnd
goto start

:exceptionEnd
echo 结束
pause
```

linux
```
while [ 1 -eq 1 ]
do
php abc.php
set last_code=$?
if [ $last_code -ne 1 ];then
echo "task error error_code: "$last_code
break
fi
done
```
