这段PHP代码会导致内存泄漏吗?
我是新手。我有这段代码需要您帮忙检查是否导致内存泄漏?这段代码的想法是检查 status.txt 文件是否不为空,然后其内容将显示在网页中,它还会检查 readmore.txt 如果该文件不为空,它将有一个指向文件的超链接。 这是代码,请帮忙
$statusfile = "status.txt";
$handle = fopen($statusfile, "r");
$string = '';
while (!feof($handle)) { $string .= fgets($handle); }
fclose($handle);
$readmore_file_path = 'readmore.txt';
$handle2 = fopen($readmore_file_path, "r");
$string2 = '';
while (!feof($handle2)) { $string2 .= fgets($handle2); }
fclose($handle2);
$strTxt = 'SYSTEM STATUS<br>';
if ('' != $string)
{
$strTxt .= $string;
if ('' != $string2) { $strTxt .= '. <a href="readmore.txt"> More details</a>'; }
$strTxt .= '<br>';
echo $strTxt;
}
I'm a newbie. I have this piece of code that need your help to check if it cause memory leak? The idea of this code is it check if the status.txt file not empty then its content will show in webpage, it also check readmore.txt if this file not empty, it will have a hyperlink to a file.
Here is the code, please help
$statusfile = "status.txt";
$handle = fopen($statusfile, "r");
$string = '';
while (!feof($handle)) { $string .= fgets($handle); }
fclose($handle);
$readmore_file_path = 'readmore.txt';
$handle2 = fopen($readmore_file_path, "r");
$string2 = '';
while (!feof($handle2)) { $string2 .= fgets($handle2); }
fclose($handle2);
$strTxt = 'SYSTEM STATUS<br>';
if ('' != $string)
{
$strTxt .= $string;
if ('' != $string2) { $strTxt .= '. <a href="readmore.txt"> More details</a>'; }
$strTxt .= '<br>';
echo $strTxt;
}

您为什么认为这段代码会导致内存泄漏?用纯 PHP 编写的任何内容都不应泄漏内存;如果 PHP 代码确实泄漏内存,那么这是 PHP 中的一个错误。
代码示例的前五行可以替换为:
同样,接下来的五行可以替换为:
请参阅:
file_get_contents()
编辑:
Why do you think that this code is causing a memory leak? Nothing that is written in pure PHP should leak memory; if PHP code does leak memory, then it's a bug in PHP.
The first five lines of your code sample can be replaced with:
Similarly, the next five lines can be replaced with:
See:
file_get_contents()
