Php CouchDB

For PHP CouchDB connectivity a PHP script is needed to be executed. By default, CouchDB executes on the port 5984. Follow the below steps for PHP CouchDB connectivity.

  • Create a Php file with the below code.
    index.php:

    <?php  
$options['host'] = "localhost";   
$options['port'] = 5984;  
$couch = new CouchSimple($options);   
$couch->send("GET", "/");   
$couch->send("PUT", "/example");   
$couch->send("PUT", "/example/100", '{"_id":"100","name":"Tom"}');   
$resp = $couch->send("GET", "/example/100");   
echo $resp;   
class CouchSimple {  
function CouchSimple($options) {  
foreach($options AS $key => $value) {  
$this->$key = $value;  
}  
}   
function send($method, $url, $post_data = NULL) {  
$s = fsockopen($this->host, $this->port, $errno, $errstr);   
if(!$s) {  
echo "$errno: $errstr\n";   
return false;  
}   
$request = "$method $url HTTP/1.0\r\nHost: $this->host\r\n";   
if ($this->user) {  
$request .= "Authorization: Basic ".base64_encode("$this->user:$this->pass")."\r\n";   
}  
if($post_data) {  
$request .= "Content-Length: ".strlen($post_data)."\r\n\r\n";   
$request .= "$post_data\r\n";  
}   
else {  
$request .= "\r\n";  
}  
fwrite($s, $request);   
$response = "";   
while(!feof($s)) {  
$response .= fgets($s);  
}  
list($this->headers, $this->body) = explode("\r\n\r\n", $response);   
return $this->body;  
}  
}  
?>
  • Access CouchDB using the URL: http://localhost:5984/_utils.
  • Check available databases.
  • Execute the PHP script at the localhost server.
  • Access CouchDB again.
  • A new database named “example” is created with a document referred to as ID 100.
  • Values stored in the document can be checked by clicking on that.
  • Fetch Data in the browser.
