Adding values to an array - php

Question

I what to get a value returned from a object method and put it into an array. The codes is as follows:
$additionalTestConfirmation = array();
$additionalTests = $this->getAdditionalTestsSelected();
foreach($additionalTests as $availableTest)
{
$additionalTestConfirmation = $availableTest->getName();
}
$appointment = $this->getAppointment();
$tokens = array(
'%DATE%' => $this->getAppointment()->getDate(),
'%LOCATION%' => $this->getAppointment()->getLocation(),
'%TIME%' => $this->getTime(),
'%ROOM%' => $this->getRoom(),
'%NAME%' => ($this->getUser() ? $this->getUser()->getFullName() : null),
'%TZ%' => $this->getAppointment()->getShowTimeZone() ? $this->getAppointment()->getTimeZone() : '',
'%AdditionalTestsSelected%' => $additionalTestConfirmation,
);
For the codes above, I got a system error message: Notice: Array to string conversion in /Users/alexhu/NetBeansProjects/menagerie/svn/trunk/apps/frontend/modules/legacy/legacy_lib/lib/classes/AppointmentTime.php on line 379.
How do I avoid this and get the $availableTest->getName() returned value I want. thanks

Answer 1

When you assign elements to an array, you must either specify an index, or use empty square brackets ([]) to add an item:
foreach($additionalTests as $availableTest) {
$additionalTestConfirmation[] = $availableTest->getName();
// or array_push($additionalTestConfirmation, $availableTest->getName());
// see: http://us3.php.net/array_push
}
See the docs for more: http://php.net/manual/en/language.types.array.php
EDIT
Also, on this line:
'%AdditionalTestsSelected%' => $additionalTestConfirmation,
... you are passing an array into this index. If the code afterword expects this to be a string, that could cause the errors. *This is not causing the error - it is perfectly acceptable to put an array in another array. As I mentioned, though, it really depends on what the code that uses the $tokens array will do and expect. If it expects a plain string for the AdditionalTestsSelected index, you might need to do this:
'%AdditionalTestsSelected%' => implode(',', $additionalTestConfirmation)
... to make the value a comma-delimited list.
Also note, at the end of that line you have an extra comma.

Answer 2

In order to add each $availableTest->getName() to the array $additionalTestConfirmation you need to use [] on your array and the assignment operator =
foreach($additionalTests as $availableTest)
{
$additionalTestConfirmation[] = $availableTest->getName();
}
You can also use the function array_push

Answer 3

foreach($additionalTests as $availableTest)
{
$additionalTestConfirmation[] = $availableTest->getName();
}
after your comment I propose you this:
$appointment = $this->getAppointment();
$token = array(
'%DATE%' => $appointment->getDate(),
'%LOCATION%' => $appointment->getLocation(),
'%TIME%' => $this->getTime(),
'%ROOM%' => $this->getRoom(),
'%NAME%' => ($this->getUser() ? $this->getUser()->getFullName() : null),
'%TZ%' => $appointment->getShowTimeZone() ? $appointment->getTimeZone() : ''
);
$tokens = array();
$additionalTests = $this->getAdditionalTestsSelected();
foreach($additionalTests as $availableTest)
{
$token['%AdditionalTestsSelected%'] = $availableTest->getName();
$tokens[] = $token;
}
// here comes logic for all tokens
