fgets read file and store into a variable

I have Multiple URL in result.txt file. I want to use first URL with fgets.

Problem is that fgets not passing value to file_get_html for next process.

$file = fopen("result.txt","r");
$link = fgets($file);
// echo fgets($file);       // Here I get URL successfully 

$html = file_get_html($link);   // Problem, Not receiving URL

foreach($html->find('.singcont a') as $a) {
    $links = $a->href;
    echo $links;
}

How to pass $link value to file_get_html ?

If I use this way it works $html = file_get_html('http://example.com/');

I'm guessing you have a newline or some other character at the end of the returned $link string.

var_dump($link);

It might output a string that looks like this:

string(19) "http://example.com
"

To remedy the issue you could either use trim() or substr():

trim ( string $str [, string $character_mask = " \t\n\r\0\x0B" ] ) : string

$link = trim($link);

substr ( string $string , int $start [, int $length ] ) : string

$link = substr($link, 0, -1);

↳ PHP Manual, trim(), substr()

You could put $html = file_get_html($link); in the for loop, so your code will be like:

$file = fopen("result.txt","r");
$link = fgets($file);
// echo fgets($file);       // Here I get URL successfully 

foreach($html->find('.singcont a') as $a) {
    $links = $a->href;
    $html = file_get_html($link);
    echo $links;
}
