PHP get_headers() fails with Pinterest -

i'm working on tool integrates link of different social networks:

facebook: https://www.facebook.com/jonathan.parentlevesque  google plus: https://plus.google.com/+jonathanparentl%c3%a9vesque  instagram: https://instagram.com/mariloubiz/  pinterest: https://www.pinterest.com/jonathan_parl/  rss: https://regex101.com  twitter: https://twitter.com/arcadefire  vimeo: https://vimeo.com/ondemand/crashtest/135301838  youtube: https://www.youtube.com/user/darkjo666 

i'm using basic regex one:

/^https?:\/\/(?:[a-z]{2}|[w]{3})?\.pinterest.com\/[\s]{5,}$/i 

on client , server side minimal domain validation on each links.

then, i'm using function validate page exists (it's useless integrate social network links don't work after all):

public static function isurlexists($url){      $exists = false;      if(!stringmanager::stringstartwith($url, "http") , !stringmanager::stringstartwith($url, "ftp")){          $url = "https://" . $url;     }      if (preg_match(regularexpression::url, $url)){          $headers = get_headers($url);          if ($headers !== false , !empty($headers)){              if (strpos($headers[0], '404') === false){                  $exists = true;             }            }     }      return $exists; } 

note: in function i'm using diego perini's regex validating url before sending request:

const url = "%^(?:(?:https?|ftp)://)(?:\s+(?::\s*)?@|\d{1,3}(?:\.\d{1,3}){3}|(?:(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)(?:\.(?:[a-z\d\x{00a1}-\x{ffff}]+-?)*[a-z\d\x{00a1}-\x{ffff}]+)*(?:\.[a-z\x{00a1}-\x{ffff}]{2,6}))(?::\d+)?(?:[^\s]*)?$%iu"; //@copyright diego perini 

all tested links far didn't generate error, testing pinterest produce me quite scary series of error messages:

get_headers(): ssl operation failed code 1. openssl error messages: error:14090086:ssl routines:ssl3_get_server_certificate:certificate verify failed  array (     [url] => https://www.pinterest.com/jonathan_parl/     [exists] =>  )  get_headers(): failed enable crypto  array (     [url] => https://www.pinterest.com/jonathan_parl/     [exists] =>  )  get_headers(https://www.pinterest.com/jonathan_parl/): failed open stream: operation failed  array (     [url] => https://www.pinterest.com/jonathan_parl/     [exists] =>  ) 

is has idea i'm doing wrong here?

i mean, ain't pinterest popular social network valid certificate (i don't use personally, created account testing)?

thank help,

i tried create self-signed certificate development environment (xampp) suggested n.b. in comment. solution didn't worked me.

his other solution use curl or guzzle instead get_headers(). not worked, but, according developper's tests:

http://php.net/manual/fr/function.get-headers.php#104723

it way faster get_headers().

for interested, here's code of new function interested:

/** * send http request $url , check header posted back. * * @param $url string url must send request. * @param $failcodelist int array list of codes page considered invalid. * * @return boolean */ public static function isurlexists($url, array $failcodelist = array(404)){      $exists = false;      if(!stringmanager::stringstartwith($url, "http") , !stringmanager::stringstartwith($url, "ftp")){          $url = "https://" . $url;     }      if (preg_match(regularexpression::url, $url)){          $handle = curl_init($url);           curl_setopt($handle, curlopt_returntransfer, true);          curl_setopt($handle, curlopt_ssl_verifypeer, false);          curl_setopt($handle, curlopt_header, true);          curl_setopt($handle, curlopt_nobody, true);          curl_setopt($handle, curlopt_useragent, true);           $headers = curl_exec($handle);          curl_close($handle);           if (empty($failcodelist) or !is_array($failcodelist)){              $failcodelist = array(404);          }          if (!empty($headers)){              $exists = true;              $headers = explode(php_eol, $headers);              foreach($failcodelist $code){                  if (is_numeric($code) , strpos($headers[0], strval($code)) !== false){                      $exists = false;                      break;                   }             }         }     }      return $exists; } 

let me explains curl options:

curlopt_returntransfer: return string instead of displaying calling page on screen.

curlopt_ssl_verifypeer: curl won't checkout certificate

curlopt_header: include header in string

curlopt_nobody: don't include body in string

curlopt_useragent: site needs function (by example : https://plus.google.com)

---

additional note: explode header string , user headers[0] sure validate return code , message (example: 200, 404, 405, etc.)

additional note 2: sometime validating code 404 not enough (see unit test), there's optional $failcodelist parameter supply code list reject.

and, of course, here's unit test legitimates coding:

public function testisurlexists(){  //invalid $this->assertfalse(toolmanager::isurlexists("woot"));  $this->assertfalse(toolmanager::isurlexists("https://www.facebook.com/jonathan.parentlevesque4545646456"));  $this->assertfalse(toolmanager::isurlexists("https://plus.google.com/+jonathanparentl%c3%a9vesque890800"));  $this->assertfalse(toolmanager::isurlexists("https://instagram.com/mariloubiz1232132/", array(404, 405)));  $this->assertfalse(toolmanager::isurlexists("https://www.pinterest.com/jonathan_parl1231/"));  $this->assertfalse(toolmanager::isurlexists("https://regex101.com/546465465456"));  $this->assertfalse(toolmanager::isurlexists("https://twitter.com/arcadefire4566546"));  $this->assertfalse(toolmanager::isurlexists("https://vimeo.com/**($%?%$", array(400, 405)));  $this->assertfalse(toolmanager::isurlexists("https://www.youtube.com/user/darkjo666456456456"));   //valid $this->asserttrue(toolmanager::isurlexists("www.google.ca"));  $this->asserttrue(toolmanager::isurlexists("https://www.facebook.com/jonathan.parentlevesque"));  $this->asserttrue(toolmanager::isurlexists("https://plus.google.com/+jonathanparentl%c3%a9vesque"));  $this->asserttrue(toolmanager::isurlexists("https://instagram.com/mariloubiz/"));  $this->asserttrue(toolmanager::isurlexists("https://www.facebook.com/jonathan.parentlevesque"));  $this->asserttrue(toolmanager::isurlexists("https://www.pinterest.com/"));  $this->asserttrue(toolmanager::isurlexists("https://regex101.com"));  $this->asserttrue(toolmanager::isurlexists("https://twitter.com/arcadefire"));  $this->asserttrue(toolmanager::isurlexists("https://vimeo.com/"));  $this->asserttrue(toolmanager::isurlexists("https://www.youtube.com/user/darkjo666")); } 

i hope solution someone,
