只要你编译完的PHP设置了支持cURL扩展，你就可以开始使用cURL函数了。使用cURL函数的基本思想是先使用 curl_init()初始化一个cURL会话，接着你可以通过 curl_setopt()设置你需要的全部选项，然后使用 curl_exec()来执行会话，当执行完会话后使用 curl_close()关闭会话。这是一个使用cURL函数获取example.com的主页保存到文件的例子：
Example #1 使用PHP的cURL模块获取example.com的主页
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
?>

Using ArangoDB with PHP
Coding with a NoSQL data base like ArangoDB can be made more complicated then need be. A simple solution to code for ArangoDB is to use the REST interface directly.
All you need is a few initialization variables and a small function to ease the typing - and of cause install the php5-curls module...
See ArangoDB REST API documentation for options and request types.
<?php
// Initialize options for REST interface
$adb_url="http://127.0.0.1:8529";
$adb_option_defaults = array(
CURLOPT_HEADER => false,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_TIMEOUT => 2
);
// ArangoDB REST function.
// Connection are created demand and closed by PHP on exit.
function adb_rest($method,$uri,$querry=NULL,$json=NULL,$options=NULL){
global $adb_url,$adb_handle,$adb_option_defaults;
// Connect
if(!isset($adb_handle)) $adb_handle = curl_init();
echo "DB operation: $method $uri $querry $json\n";
// Compose querry
$options = array(
CURLOPT_URL => $adb_url.$uri."?".$querry,
CURLOPT_CUSTOMREQUEST => $method, // GET POST PUT PATCH DELETE HEAD OPTIONS
CURLOPT_POSTFIELDS => $json,
);
curl_setopt_array($adb_handle,($options + $adb_option_defaults));
// send request and wait for responce
$responce = json_decode(curl_exec($adb_handle),true);
echo "Responce from DB: \n";
print_r($responce);
return($responce);
}
?>
Here's some examples:
<?php
// Create a collection
$responce = adb_rest("POST","/_api/collection","",'{"name" : "test"}');
// Create a document
$responce = adb_rest("POST","/_api/document","collection=test",'{ "hello" : "World" }');
// List documents in a collection
$responce=adb_rest("GET","/_api/document","collection=test");
// Change document
$document_handle=$responce['documents'][0];
$responce=adb_rest("PATCH",$document_handle,"",'{ "hello" : "World of mine" }');
// Show document
$responce=adb_rest("GET",$document_handle);
// Search
$responce=adb_rest("POST","/_api/cursor","",'{
"query" : "FOR t IN test RETURN t",
"count" : true,
"batchSize" : 50
}');
while($responce['hasMore'])
$responce=adb_rest("PUT","/_api/cursor/".$responce['id']);
// Delete document
$responce=adb_rest("DELETE",$document_handle);
// DB Delete collection
$responce=adb_rest("DELETE","/_api/collection/test");
// to handle errors, add something like this:
if($responce['error']) die ("can't create collection");
?>
