gossamer1 Posted June 16, 2020 Share Posted June 16, 2020 Hi, I'm a PHP novice and trying to print out elements of what appears to be a multi-dimensional array, but I can't figure it out.

our contacts using the vendor's PHP API, but I'm not much of a PHP programmer. The array is stored in $contacts, using the vendor's getList() function. I believe I'm able to download the whole list of contacts in an array, but I can't iterate through it. I'd like to print out the elements of the array in CSV format. This looks like some complicated multidimensional array. I also have no idea what the array keys are ('isPublished', etc). $contacts = $contactApi->getList($searchFilter, $start, $limit, $orderBy, $orderByDir, $publishedOnly, $minimal); foreach ($contacts as $var) {    echo "\n", $var['isPublished'], "\t\t", $var['value']; } I've also tried something like this: foreach ($contacts as $contact) {   echo "\n", $contacts[$contact['isPublished']]; } Other ideas greatly appreciated.     Quote Link to comment https://forums.phpfreaks.com/topic/310947-printing-elements-of-an-array/ Share on other sites More sharing options...

gossamer1 Posted June 16, 2020 Author Share Posted June 16, 2020 Thank you for your help - I don't understand 😞 Maybe something like this?  $contacts = $contactApi->getList($searchFilter, $start, $limit, $orderBy, $orderByDir, $publishedOnly, $minimal); foreach ($contacts as $var) {    echo "\n", $contacts[$var]; } Except that prints the following: PHP Notice:  Undefined offset: 18733 in export.php on line 76 PHP Warning:  Illegal offset type in export.php on line 76   Quote Link to comment https://forums.phpfreaks.com/topic/310947-printing-elements-of-an-array/#findComment-1578943 Share on other sites More sharing options...
maxxd Posted June 17, 2020 Share Posted June 17, 2020 foreach() the way you're using it is going to pass each individual value of the array into the function body, so you don't need to reference $contacts[$var]. I assume the first value in your $contacts array is '18733', right? But there's probably not an index of 18733 in the $contacts array. Try this: foreach($contacts as $var){ echo $var.PHP_EOL; } You should see each value of your array on a separate line.
