php ob_flush

How to show your script output as it is producing it. Normally everything is buffered and shown all at once, but sometimes you want to show the actual progress of the script.
This needs a few steps to get it working.

Icepay cURL 60 SSL problem

To be precise, the error is: “Unable to reach the ICEPAY payment server (60):SSL certificate problem: unable to get local issuer certificate“

The solution could be:

curl_setopt($this->ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, 0);

or, which also works in my case:

curl_setopt($this->ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($this->ch, CURLOPT_SSL_VERIFYPEER, false);

Of course bypassing SSL security is never the correct option, but for a development server we all make exceptions sometimes.
Have a nice day!

PHP variables and strings

Sometimes you have to be reminded of the basics:

“How to use a dollar-sign $ in a string?”
In single quotes a dollar sign isn’t parsed as anything. Nothing is auto parsed in single quotes in php. If you use double quotes they are automatically parsed:

echo "$var"; // this will print the value of $var;
echo '$var'; // this will print $var;
echo "\$var";// this escapes the dollar sign so it will print $var;

MySQL user not connecting

Problem:
Windows Server 2016, IIS Website, Setup a MySQL server/database, setup a WordPress website, quickly connect with root and root-password. Everything works fine!

Now you want things more secured, so you add a MySQL user with a password and rights to only the wordpress database. Change wp-config.php with the new login and you get a “Error Establishing a Database Connection” when accessing the WordPress website or admin.

Change back to root and the problem is solved. How to fix this?

Display all PHP Errors and Warnings

When debugging PHP I find myself searching again and again for this little piece of code to display the PHP errors. So here it is for future reference…
If you wish to see all the PHP errors and warnings in your script, simply include the following bit of code:

error_reporting(E_ALL);
ini_set(‘display_errors’, ‘1’);

Now, continue to beat your head against the keyboard while you hunt down that missing semicolon or closing parenthesis. Need help, contact My Brain.
