无法使用php驱动程序删除mongodb中的文档

Question

Here is the structure of my document in mongo.

{
"_id": {
    "$oid": "52c7ab89e4b079616e8e4be4"
},
"memberId": 1,
"memberName": "Hannan Shaik",
"memberEmail": "XXX@example.com",
"memberPhone": "123456"
}

PHP Code to remove this record is

$memberId=1;
$collection->remove(array('memberId' => $memberId), array("safe" => true));

This is not removing the document. Whereas, below statement does.

 $collection->remove(array('memberId' => 1), array("safe" => true));

Kindly explain as to what is the cause for this?

Please note I cannot directly give the memberId value as the above statement is written in a function that is passed with a value in $memberId.

Answer 1

It was a miss to check if the $member was a number or string.

The value is $member was a string. Hence the issue.
