PHP operation MongoDB Database specific sample introduction (increase, delete, change, check) (vi)

PHP Operation MongoDB:

PHP need to play module to operate MongoDB
Official website can download: Http://pecl.php.net/package/mongo download

MongoDB is set to user-authorized startup mode

PHP Manual does not have the user authorization method to log in:
conn.php
<?

Php
$conn = new Mongo ("Mongodb://user1:[email protected]:27017/test"); User Authorization link MongoDB test database
$db = $conn->test;
?>

find.php
<?php
Include "conn.php";
$c 1 = $db->c1; Operation C1 Collection

Because PHP can't use JSON directly
Db.c1.find ({name: "user1"}); Can't play like this.
{name: "user1"} = = Array ("name" = "user1") in this form
[up] = = Array (up);
{} = = Array ()

$arr =array ();
$rst = $c 1->find ($arr);
foreach ($rst as $val) {
echo "<pre>";
Print_r ($val [' name ']); "_ID" to take the ID.
}


Example 2: Specifying a value query
$arr = Array ("name" = "user1"); Query the Nam=user1
$rst = $c 1->find ($arr);
foreach ($rst as $val) {
echo "<pre>";
$fis = $val [' _id '];
Print_r ($val);
echo "<a href= ' user.php?"

fid={$fid} ' ></a> '; You will find that the FID has passed into the user.php when it becomes a string. How to solve?
user.php according to _id to search MongoDB corresponding data
<?php
Include "conn.php";
$c 1 = $db->c1;
$oid = new MongoId ($_get[' fid '); Use this to turn around.
Var_dump ($oid); or object, which is the string type.

$arr = Array ("_id" = "$oid");
$rst = $c 1->find ($arr);
foreach ($rst as $val) {
echo "<pre>";
Print_r ($val);
}
?>
}


Example 3: Adding
Include "conn.php";
$c 1 = $db->c1;
Db.c1.insert ({"Name" = "User3", age:30, "sex" = "Nan"});
$arr = Array ("name" = "User3", "Age" =>30, "sex" = "Nan");
if ($c 1->insert ($arr))
echo ' success ';
Else
echo ' failure ';




Example 4: Delete
Include "conn.php";
$c 1 = $db->c1;
Db.c1.remove ({"Name" = "User2"});
$arr = Array ("name" = "User2");
if ($c 1->remove ($arr))
Echo ' Delete succeeded ';
Else
Echo ' delete failed ';




Example 4: Change
Include "conn.php";
$c 1 = $db->c1;
Db.c1.update ({"Name" = "User2"},{$set: {age:20,sex: "Nan"}}); Add Field
$sarr = Array ("name" = "User2");
$darr = Array (' $set ' =>array (' sex ' = ' nan ', ' age ' =>24));
$opts = Array (' Upsert ' =>0, ' multiple ' =>1);
if ($c 1->update ($sarr, $darr, $opts)) The update in//php can only pass 3 of the parameters
Echo ' Change succeeded ';
Else
Echo ' Change failed ';

Shut down
$conn->close ();
