php include 错误

真心不明白怎么回事,代码如下
if(file_exists('perform.php'))
echo '3';
include 'perform.php';
echo "hi1";
if(isset($_POST['target']))perform($_POST['target']);
?>
perform.php文件是存在的,但是页面显示3,不显示hi1
求大神……!!
------解决方案--------------------
你怎么确定没执行的。查看源码就知道了。

注释掉include是什么情况
------解决方案--------------------

引用:
引用:引用:引用:显示3 有什么不对,if 条件满足啊。

如果有错误请贴出
问题在于……include下面的语句没有执行啊……
那就要把perform.php的代码贴出来看看啊,会不会已经exit了
function perform……


foreach($bar as mysql_fetch_array($result))
反了

foreach(mysql_fetch_array($result) as $bar)
------解决方案--------------------
引用:
引用:引用:引用:引用:引用:显示3 有什么不对,if 条件满足啊。

如果有错误请贴出
问题在于……include下面的语句没有执行啊……
那就要把perform.ph……


问题还是在你这个包含文件里,即使只是函数没有被执行,但是有一个地方出错也会导致include出错的,继续找找其他地方有没有语法错误吧,跟着错误提示走就行了

How to calculate the total number of elements in a PHP multidimensional array?How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.
