How to print a specific value in array in PHP?
提问by cateye
array(2) {
[0]=>
object(stdClass)#144 (7) {
["id"]=>
string(1) "2"
["name"]=>
string(8) "name1"
["value"]=>
string(22) "Lorem Ipsum Dolar Amet"
["type"]=>
string(8) "textarea"
["group"]=>
string(1) "1"
["published"]=>
string(1) "1"
["ordering"]=>
string(1) "1"
}
[1]=>
object(stdClass)#145 (7) {
["id"]=>
string(1) "4"
["name"]=>
string(6) "Link1"
["value"]=>
string(36) "abcabcab"
["type"]=>
string(4) "link"
["group"]=>
string(1) "1"
["published"]=>
string(1) "1"
["ordering"]=>
string(1) "2"
}
}
I want to print only "value" (abcabcab) of id=4. How can I achieve this?
我只想打印 id=4 的“值”（abcabcab）。我怎样才能做到这一点？

foreach ($array as $entry) {
if ($entry['id'] == 4)
echo $entry['value'];
}

foreach($array as $row){
if($row['id']==4){
print($row['value']);
}
}

this works:
这有效：
foreach ($array as $entry) {
if ($entry->id == 4)
echo $entry->value;
}
Thanks!
谢谢！
回答by Matthew Flaschen
array_walk($a, function($el){if($el->id === 4){print $el->value;}});
