Switch Off Foreign Key Constraint

I used to use this code regularly but when i found it for the first time it took me to read many pages to read after getting the code i thought this would be useful for all people like me who want to Switch off the Foreign key Constraint in their tables

This is helpful when you are actually want to create tables irrespective of the Foreign key constraint

To Turn Off - SET FOREIGN_KEY_CHECKS = 0;

To Turn On - SET FOREIGN_KEY_CHECKS = 1;

Difference between Echo and Print in Php

We have Echo we have print in php which we use to display the output to the user

Both Echo and Print does the same work - Displaying the output on the screen

But there are couple of differences between them

Echo

Output one or more strings
Allows More parameters works only with the short open tags
It is not a function
It takes less memory

Print

Output only one string
It allows only one parameter
Its not a real function but its a language construct
It take a little more memory than echo

Curl Using PHP in a Gist

cURL: It is a client that deals with URL so its named as cURL so as to say that it deals with URL only

It is used to make client communicate with the server using command line
arguments using cURL syntax

Its main use is to provide security to the URL's sent through the browser to the server

The main commands in cURL which i found is important are

1. curl_init() - with which the main curl operation starts

2.curl_setop($charecter,options,value) -

$charecter = curl handle returned by curl_initi()

options = curl provides various options with general syntax
