foreach as key value code example

Example 1: javascript foreach get key and value

myObject ={a:1,b:2,c:3}

//es6
Object.entries(myObject).forEach(([key, value]) => {
  console.log(key , value); // key ,value
});

//es7
Object.keys(myObject).forEach(key => {
    console.log(key , myObject[key]) // key , value
})

Example 2: php loop through array

$clothes = array("hat","shoe","shirt");
foreach ($clothes as $item) {
	echo $item;
}

Example 3: foreach key value javascript

const object1 = {
  a: 'somestring',
  b: 42
};

for (let [key, value] of Object.entries(object1)) {
  console.log(`${key}: ${value}`);
}

// expected output:
// "a: somestring"
// "b: 42"
// order is not guaranteed

Example 4: php foreach

<?php
$age = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43");

foreach($age as $x => $val) {
  echo "$x = $val<br>";
}
?>
