php include require

includ和require都是把其他页面加载当前页面，不过不同的是，require如果没有找到，或者所包含的页面里面有错误就不会往下执行了

<?php
    include ‘form.php‘;
    
    require ‘aasdfa.php‘;
?>

form.php 存在所以没有问题

aasdfa.php没有所以报错了

Warning: require(aasdfa.php): failed to open stream: No such file or directory in D:\phpStudy\WWW\learn\includ_require.php on line 4

Fatal error: require(): Failed opening required ‘aasdfa.php‘ (include_path=‘.;C:\php\pear‘) in D:\phpStudy\WWW\learn\includ_require.php on line 4
