How can I update this array?
Posted on 2016-09-04
Here's my array when I do a var_dump:
array (size=3)
'eventdate' => string '2016-08-27' (length=10)
'eventtype' => string 'transaction' (length=11)
'runningbal' => string '32.50' (length=5)
The name of the array is "$event."
I need to update "eventtype." My plan was to do a "foreach" in order to isolate each of the variables and then change "transaction" to "payment."
When I do this:
foreach($event as $sport)
{
echo $sport['eventtype'];
}
I get this: Warning: Illegal string offset 'eventtype' in C:\wamp\www\patient_focus\
What am I doing wrong?

But if you need to iterate throught the array you can do it this way:
foreach ($event as $key => $value) {
if ($key == 'eventtype') {
echo $value;
}
}

Please use var_export() to print out your test data in the $event array, and post that output here in the code snippet. Then we can see (and code) with exactly the same information you're using.

@Ray sorry, but I don't understand your point: Bruce is just using a wrong code within the foreach loop... He has just to use $event['eventtype'] to get that element.
@brucegust: Here the working code to update array - nothing esoteric :)

<?php
error_reporting(E_ALL);
ini_set('display_errors', 'On');
$event = array(
'eventdate' => '2016-08-27',
'eventtype' => 'transaction',
'runningbal' => '32.50',
);
echo "Original array:<br>";
echo "<pre>";
var_dump($event);
echo "</pre>";
echo "Going to change event type to payment (\$event['eventtype'] = 'payment';)<br>The array after the change:<br>";
$event['eventtype'] = 'payment';
echo "<pre>";
var_dump($event);
echo "</pre>";

Hi, Marco. There have been various iterations of this question. Some of them have used multidimensional arrays. I'm just wondering if this $event is really an excerpt from a larger data set, or if it has been copied from a larger data set, or otherwise exists in a different form than we see here. I have a feeling that there may be more to it than is present inside the four corners of this question.
And in any case, when we can get the author of a question to understand the value of showing us the test data (instead of showing us non-working code, or a partial description of the test data, or any of a number of other non-helpful things) then we have made progress for everyone. And if the author uses var_export() PHP will give us a piece of working code that we can copy/paste and test with immediately. It's a "help us help you" request.

Ah, I see. I had got the second part of your explanation, but I didn't consider the possibility that the array $event were part of a larger data set... As usual, good point, Ray :)

Ray, I thought I had nailed it by doing a var_dump()! Well, nuts! As it turns out, Marco was able to give me what I needed, so I'm good, however...

...and I make a point of doing var_export.
Thank you!
