How to Make a Query in CakePHP?

CakePHP

To Query from Table in CakePHP we can use the below code. We can also Query like ORDER_BY, Select Table FIELDS etc.

# Find Order from Order Table in CakePHP

$this->Order->find('all', array(
   'recursive' => -1,
   'conditions'=>array( 'Order.id'=>1 ),
   'fields' => array( 'Order.date', 'Order.id', 'Order.total'),
   'order' => array('Order.date' => 'DESC'),
));

How to Get the Header Data CakePHP or PHP?

I Personally Tried a lot for getting the posted header data in cakephp.

The Header data required to check the posted token. Token validation , to check the posted request is valid or not.

Finally I found the Solution.
PHP It self has a function named, getallheaders()

Syntax: getallheaders ( void ) : array
Description: Fetches all HTTP headers from the current request.

Return Values::
An associative array of all the HTTP headers in the current request, or FALSE on failure.

Example #1 getallheaders() example

$headers = getallheaders();
foreach( $headers as $name => $value) {
     echo "$name: $value\n";
}

Example: Received Data:

Array
(
     [Host] => 127.0.0.1
     [Connection] => keep-alive
     [Content-Length] => 264
     [auth_token] => 20dea7c13dada345dgf80815d3546393a98
     [device_id] => adada23456
     [Cache-Control] => no-cache
     [Origin] => chrome-extension://fhbjgjbdggehcddcbncdddomop
     [User-Agent] => Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36
     [Postman-Token] => 2d5b612b-e2db-1202-50f1-925cb2f8fa05
     [Content-Type] => multipart/form-data; boundary=----WebKitFormBoundarySssj4jB1U7xNxnHy
     [Accept] => */*
     [Accept-Encoding] => gzip, deflate, br
     [Accept-Language] => en-GB,en-US;q=0.9,en;q=0.8

How to Create Unique Number in PHP?

Option-1:

$mt_rand = mt_rand(1000000000, 9999999999); 
echo $mt_rand;

Option-2:

$unique_id = uniqid();
echo $unique_id;
 uniqid( prefix, more_entropy ) 

prefix:
Can be useful, for instance, if you generate identifiers simultaneously on several hosts that might happen to generate the identifier at the same microsecond.

With an empty prefix, the returned string will be 13 characters long. If more_entropy is TRUE, it will be 23 characters.

more_entropy:
If set to TRUE, uniqid() will add additional entropy (using the combined linear congruential generator) at the end of the return value, which increases the likelihood that the result will be unique.

source: https://www.php.net/manual/en/function.uniqid.php

Option-3:

$mt_rand = mt_rand(1000000000, 9999999999);
$timestamp = time();
$temp = $mt_rand + $timestamp;
$temp2= substr($tmp, 0,10);

echo $temp2;
