file_get_contents() expects parameter 1 to be a valid path, array given in a php file-CodePudding

I have a php code as shown below in which I extracting a title from a good.php file.

good.php

print_r($good_files);   // Line Y

$good_title = ExtractGoodTitle($good_files);  // Line Z
        
function ExtractGoodTitle($filename)
{
    $html = file_get_contents($filename);   // Line A
    .
    .
    .
    .
    .
    .
    .
    .
    return $title;
}

At Line A, I am getting the following error: file_get_contents() expects parameter 1 to be a valid path, array given in ./good.php file.

For debug purpose, I have added print_r($good_files) in the code. Line Y prints the following:

Array ( [180] => /home/alex/public_html/good/web/gooddump/GOOD_2.html 
        [375] => /home/alex/public_html/good/web/gooddump/GOOD_4.html

        [170] => /home/alex/public_html/good/web/gooddump/GOOD_28.html 
    )

Problem Statement:

I am wondering what changes I need to make in the php code at Line Z or Line A so that it doesn't throw the error.

CodePudding user response：

You need to iterate over the $good_files array as such, since it is an array you will get a lot of titles, not only one.:

foreach ($good_files as $good_file) {
    $good_title = ExtractGoodTitle($good_file); 
}
