help me, how to find text on an external html site using PHP

[syam92]

Would anyone know how to search an external html file for a work or phrase ?

 

I was thinking something like this --

I use script cURL...

 

<?php
if (isset($_POST['submitted'])) {

    $xurl_1 = $_POST['url_1'];
    $xtext_1 = $_POST['text_1'];

    function check_1($url_1, $text_1){
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL,$url_1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
        $result=curl_exec ($ch);
        curl_close ($ch);
        
        preg_match ("|<[pP]>".$text_1."<\/[pP]>|i", $result, $matches);
        
        if (count($matches)>0){
            $i=true;
        }else{
            $i=false;
        }
        return $i;
    }
    
    if(check_1( $xurl_1, $xtext_1)){
        echo "Text found";
    }else{
        echo "Text not found";
    }

} else {
?>

      <h3>Link Verifier</h3>
      <form action="<?php $_SERVER['PHP_SELF']; ?>" method="post">
      <p><b>URL :</b> <input type="text" name="url_1" size="30" value="" /></p>
      <p><b> Exist :</b> <input type="text" name="text_1" size="30" value="" /></p>
      <div align="center"><input type="submit" name="submit" value="Check" /></div>
      <input type="hidden" name="submitted" value="TRUE" />
      </form>
      <?php
      }
      ?>

 

Unfortunently, that doesn't work..

 

it say:

"Fatal error: Call to undefined function curl_init() in /home/*/*/new.php on line 8"

 

how to install cURL on windows?

it comes bundled with php5.. open your php.ini and uncomment this line:

 

;extension=php_curl.dll
