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 ?

$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];

I don't understand you only have to do

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

for example

Use if with in_array. This will only print a and apple

foreach($foo as $key => $item) {
   if(!in_array($key,array('b','c'))) {
       echo $key;
       echo $item;
   }
}

Output

a
apple

Codepad

I understand you're only interested in the first key and value.

First value:

echo current($foo);

First key:

echo key($foo);

foreach($data as $value)
  if($value['email']==$value) {
    $selected='selected';
  } else {
    $selected='';
  }
