Get all links with Selenium in PHP

selenium_links.php

require_once "phpwebdriver/WebDriver.php";

$webdriver = new WebDriver("localhost", "4444");
$webdriver->connect("firefox");         

$webdriver->get("http://slashdot.org");

$links = $webdriver->findElementsBy(LocatorStrategy::tagName, "a");

$getLinksScript = <<<EOT
var linkTags = document.getElementsByTagName('a');
var links = [];
for ( var i = 0; i < linkTags.length; i++ ) {
  var href = linkTags[i].href;
  if ( href ) {
    links.push(href);
  }
}
return links;
EOT;
  
$href = $webdriver->executeScript($getLinksScript, array());
print_r($hrefs);

how about this?

if (count($driver->findElements(WebDriverBy::xpath("//a[@href]"))) != 0){
    $links = $driver->findElements(WebDriverBy::xpath('//a[@href]'));
    foreach ($links as $key => $value) {
        echo $value->getAttribute('href') . "\n";
    }
}
