PHP代码从.php文件中获取字符集给出错误消息

Thanks in advance.

Getting this warning when using below code:

Warning: file_get_contents(test.php) [function.file-get-contents]: failed to open stream: No such file or directory in /path/index.php on line so-n-so.

Here's the code I am using,

<?php

// Scan directory for files
$dir = "path/";
$files = scandir($dir);

// Iterate through the list of files 
foreach($files as $file)
{
// Determine info about the file
$parts = pathinfo($file);

// If the file extension == php
if ( $parts['extension'] === "php" )
{
// Read the contents of the file
$contents = file_get_contents($file);

// Find first occurrence of opening template tag
$from = strpos($contents, "{{{{{");

// Find first occurrence of ending template tag
$to = strpos($contents,"}}}}}");

// Pull out the unique name from between the template tags
$uniqueName = substr($contents, $from+5, $to);

// Print out the unique name
echo $uniqueName ."<br/>";
}
}
?>

The error message says that the file isn't found.

This is because scandir() returns only the basename of the files from your directory. It doesn't include the directory name. You could use glob() instead:

$files = glob("$dir/*.php");

This returns the path in the result list, and would also make your extension check redundant.

I would suggest that you need to exclude . and .. from the list of files picked up by scandir() ^DOCs.

// Iterate through the list of files 
foreach($files as $file) {
    if('.' == $file or '..' == $file) {
        continue;
    }
...

Also you need to put the path before your file name:

$contents = file_get_contents($path . $file);
