I am attempting to debug a php script I did not write. In order to check if a location already exists, they used the following:
$locTable = JTable::getInstance('Location', 'DPCalendarTable');
if ($locTable->load(array('latitude' => $data['latitude'],'longitude' => $data['longitude'])){
$_eventLocCache[$data['alias']] = (int)$locTable->id;
}
What is the purpose of "..->load(array..."?
Since you use Joomla it retrieves data from the table called Location
JTable::load() - Loads a row from the database and binds the fields
to the object properties.

I was trying to build a script that could get me definitions of words from the wikipedia API in php.
I tried several obtaining the definitions in an array and displaying the first definition but it didn't work. Can anyone please help me out. Any help is appreciated
Which parameters did you use in your request?
You can take this as an example:
https://en.wikipedia.org/w/api.php?action=opensearch&search=PHP&limit=1&format=json
You said there that you want only the first definition, so you can put limit=1. The response is in json.

Have you also edited that twig file via the built in editor in Design > Theme Editor? If so, it will use that one (which is stored in the database) rather than the file itself.

I pass a variable called txt from one query on a web page to another web page using
<?php echo $_GET['txt'];?>
the problem some time the text will have a word like don't in it. the (') causes things to just stop. I need to output the variable as read from the database which would include any text that was in the field
When using $_GET you should use urlencode() and urldecode().

I have thousands of files sitting in a MYSQLi database with extension .BLAH . I need to change the extension for all those files to .BLAH2 .
What would be the easiest way to accomplish this?
Many thanks for reading.
You can achieve this with a simple update set and replace.
UPDATE files set file = replace(file, 'blah', 'blah2')
