php怎样在局部include

1、话不多说，直接上代码

test.php

<?php

header("Content-type: text/html; charset=utf-8");

echo "hello";

echo "<br />";

include("param.php");

echo "<br />";

echo "hello";

echo "<br />";

echo "我有一辆".$car."它是".$color."的";

?>

2、param.php

<?php

$color = "红色";

$car = "小轿车";

echo "我是引入的文件";

?>

3、引用成功执行结果，如下图所示

4、如果在引用之前使用变量会报错

<?php

header("Content-type: text/html; charset=utf-8");

echo "hello";

echo "<br />";

echo "我有一辆".$car."它是".$color."的";

echo "<br />";

include("param.php");

echo "<br />";

echo "hello";

echo "<br />";

echo "我有一辆".$car."它是".$color."的";

?>

5、如果在引用文件中打了断点，那么会导致之后的代码不会执行

param.php

<?php

$color = "红色";

$car = "小轿车";

exit;

echo "我是引入的文件";

?>

test.php

<?php

header("Content-type: text/html; charset=utf-8");

echo "hello";

echo "<br />";

include("param.php");

echo "<br />";

echo "hello";

echo "<br />";

echo "我有一辆".$car."它是".$color."的";

?>

6、执行结果如下图所示。
