Execute a HTTP POST Using PHP CURL from one PHP to other.

By Devang | October 17, 2008

I had a typical issue in my project where i had to pass request variables from one PHP to other with using FORM tag.
Example flow

a.php gets parameters from client passes it to b.php
b.php gets the params and had to pass those to c.php without people knowing.

It may seem easy but i had to scratch my hairs for a possible solution. (I am a begineer in PHP)

I thought about all of the possible solutions for solving this challenge and settled on this flow:

User will submit the form, as usual from a.php.
In the form processing b.php, I use CURL to execute a POST transmission to a c.php.

Code for b.php

$post=array('a'=&gt;'b','c'=&gt;'d');
foreach($post as $key=&gt;$value) { $post_string .= $key.'='.$value.'&amp;'; }
rtrim($post_string,'&amp;');
 
$ch = curl_init();
 
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,'c.php');
curl_setopt($ch,CURLOPT_POST,count($post));
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_string);
 
//execute post
$result = curl_exec($ch);
 
//close connection
curl_close($ch);

This solution worked quite well so I thought I’d share it with you. Here’s how you execute a POST using the PHP CURL library.

WAMP and phpMyAdmin #1045 Access denied for user ‘root’@'localhost’ (using password: NO) problem’s Solution

By Devang | October 17, 2008

Most of the people who are new to wamp do get this problem. I faced the similar problem. I setup wamp on my XP machine and everything ran fine.

I went into phpmyadmin and it gave me a warning that I should put a password up for mysql, otherwise people could just log right in, so I changed the password within phpmyadmin.

I opened D:\wamp\apps\phpmyadmin2.11.6\config.inc.php file and changed the password in config.inc.php by modifying $cfg['Servers'][$i]['password'] = ”; line to $cfg['Servers'][$i]['password'] = ‘devang’;

When i opened phpMyAdmin again it threw an error as

“MySQL said:
#1045 - Access denied for user ‘root’@'localhost’ (using password: NO)”

I scratched my head and did some googling. I found out a solution to this problem.

My mistake was that i changed the password in config.inc.php but i didn’t changed it for mysql.
So I went to “D:\wamp\apps\mysql\bin” and executed the following command at cmd prompt.

D:\wamp\apps\mysql\bin> mysql -u root

It gave me mysql prompt.
At mysql prompt i executed
mysql> SET PASSWORD FOR ‘root’@'localhost’ = PASSWORD(’devang’);

Then i restarted all wamp services and opened phpMyAdmin and to my surprise it opened.
I had successfully changed the root password.

To summarize the steps

Open config.inc.php from Wamp installation and change set the password in the line $cfg['Servers'][$i]['password'] = ”;
Change MYSQL password for root by going to mysql\bin directory and execute “mysql -u root” at cmd prompt. This will give you mysql prompt.
At mysql prompt execute SET PASSWORD FOR ‘root’@'localhost’ = PASSWORD(’desired_password’);
Restart all wamp services and you are done.
