The following code gives the expected results:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Generate Description and Tags</title>
</head>
<body>
<?php
include 'simple_html_dom.php';
$entityURL = "http://google.com";
echo "Entity URL: ", $entityURL,"<br>";
$html = file_get_html($entityURL);
$tot_html_str = $html->save();
$tot_html_strlen = strlen($tot_html_str);
echo "Strlen of total HTML: ",$tot_html_strlen,"<br>";
?>
</body>
</html>
results in:
Entity URL: http://google.com
Strlen of total HTML: 7403
However, if I read the URL from a file, I am not able to scrape the HTML:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Generate Description and Tags</title>
</head>
<body>
<?php
include 'simple_html_dom.php';
$myFile = "/home/prakash/foo.txt";
$src_handle = fopen($myFile, "r");
$entityURL = fgets($src_handle, 4096);
echo "Entity URL: ", $entityURL,"<br>";
$html = file_get_html($entityURL);
$tot_html_str = $html->save();
$tot_html_strlen = strlen($tot_html_str);
echo "Strlen of total HTML: ",$tot_html_strlen,"<br>";
?>
</body>
</html>
results in:
Entity URL: http://google.com
Strlen of total HTML: 0
What do I need to do differently to read the URL from a file.
