Php foreach循环键打印特定值[关闭]

Question

i'm trying to get individual values from an php foreach loop.

My code is

$foo = array('a' => 'apple', 'b' => 'ball', 'c' => 'coke');

foreach($foo as $key => $item) {
  // Need to display only one array value any key like below,
  // First entry Key : a
  // First entry value: apple
}

Help me to do this ?

Answer 1

$foo = array('a' => 'apple', 'b' => 'ball', 'c' => 'coke');

foreach($foo as $key => $item) {
  echo $key;
  echo $item;
}

will output

a apple b ball c coke

or if you want the first item only, use

echo $foo['a'];

will output

apple

or to get the first array item without knowing the key

$keys = array_keys($foo);
$values = array_values($foo);
echo $keys[0];
echo $values[0];
