所以我正在学习php,并试图为一个网页做一个php点击计数器。现在,我已经根据我的理解编写了这段代码。问题是,当我在终端中运行程序时,我得到了正确的答案(输出与我预期的一样)。当我在html页面上做回显时,它不工作。以下是代码
<html>
<body>
<?php
#open the file (assuming this file already exists with only 0 in it)
$file = 'test.txt';
$file = fopen($file,"r");
$temp = fread($file, 1024);
fclose($file);
#save the number 0 (initial counter to $temp) and delete it)
$file = 'test.txt';
unlink($file);
#open the file (this line just creates the file to write)
$file = fopen("test.txt","w");
fclose($file);
#increase the counter by a number (10 for testing)
$temp = (int)$temp + 10;
$file=fopen("test.txt","w");
fwrite($file,"$temp \n")
fclose($file);
#the file only contains a number ($temp - the final counter)
echo "<h1>$temp<h1>"; #this outputs the correct counter in terminal but only outputs 10 on html page. ?????
?>
</body>

我认为这是权限问题。尝试更改chmod/chown,例如:
sudo chown coders:www-data test.txt
sudo chown 765 test.txthttps://stackoverflow.com/questions/19991423
