Simple HTML DOM - Failed to open stream: Connection Timeout - php

Question

Hello I hosted my website into a free hosting site (5gbfree.com) and I created here a function where it retrieves the Peso-dollar rate based from the site http://ppa.com.ph??q=fcer_view where it simply select the a.active element and get the value as plaintext. It was working yesterday but when I checked it our again this morning it failed to fetch. So it will return the default value which is 50.
error_log:

I am using simple html DOM.
Here's the function.
include "simple_html_dom2.php";
function PPA_peso_dollar_rate(){
// Create DOM from URL or file
error_reporting(E_ALL);
ini_set("display_errors", 0);
ini_set('default_socket_timeout', 15);
$html = file_get_html("http://www.ppa.com.ph/?q=fcer_view");
$ret = 0;
if($html === false){
$ret = 50;
}else {
foreach($html->find('a[class=active]') as $e)
$ret = $e->plaintext;
$explode = explode(" ", $ret);
$ret = 50;
foreach($explode as $ex){
if(is_numeric($ex)){
$ret = $ex;
}
}
if($ret == 0) $ret = 50;
}
echo $ret;
}
Unfortunately 5gbfree disabled curl_init() function.
curl_init() has been disabled for security reasons in /home/rasibaseport/public_html/config.php on line 38
Is there any work a round here? I appreciate any help. Thank you very much.
Edit: I forgot to mention that testing this with localhost(xampp), the expected return value is correct with no errors and warnings. Works perfectly fine.
UPDATE: After trying #Rafiq's updated solution, nothing worked. It gave me similar error.

Answer 1

Your code is work for me. Its problem in execution time. Add the following code to increase maximum execution time.
ini_set('max_execution_time', 300); //300 seconds = 5 minutes
ini_set('default_socket_timeout', 100); // 100 seconds = 1 Minutes 40 sec
//call the function file_get_html();
Explanation of parameter max_execution_time inside ini_set finction
This sets the maximum time in seconds a script is allowed to run before it is terminated by the parser. This helps prevent poorly written scripts from tying up the server. The default setting is 30. For detail read Runtime Configuration
To get rid of the following two error use fetch_http_file_contents($url) instead of file_get_contents($url) inside simple_html_dom.php on line 75.
file_get_contents(): failed to open stream: No route to host
file_get_contents(): failed to open stream: Connection timed out
function fetch_http_file_contents($url) {
$hostname = parse_url($url, PHP_URL_HOST);
if ($hostname == FALSE) {
return FALSE;
}
$host_has_ipv6 = FALSE;
$host_has_ipv4 = FALSE;
$file_response = FALSE;
$dns_records = dns_get_record($hostname, DNS_AAAA + DNS_A);
foreach ($dns_records as $dns_record) {
if (isset($dns_record['type'])) {
switch ($dns_record['type']) {
case 'AAAA':
$host_has_ipv6 = TRUE;
break;
case 'A':
$host_has_ipv4 = TRUE;
break;
} } }
if ($host_has_ipv6 === TRUE) {
$file_response = file_get_intbound_contents($url, '[0]:0');
}
if ($host_has_ipv4 === TRUE && $file_response == FALSE) {
$file_response = file_get_intbound_contents($url, '0:0');
}
return $file_response;
}
function file_get_intbound_contents($url, $bindto_addr_family) {
$stream_context = stream_context_create(
array(
'socket' => array(
'bindto' => $bindto_addr_family
),
'http' => array(
'timeout'=>20,
'method'=>'GET'
) ) );
return file_get_contents($url, FALSE, $stream_context);
}
