torrent kitty search PHP array traversal method list foreach, list, each

Arrays are divided into two categories in PHP: numerically indexed arrays and associative arrays.
The numerical index array is the same as the array in C language, the subscripts are 0, 1, 2...
The subscript of the associative array may be of any type, similar to hash, map and other structures in other languages.
The following introduces three methods of traversing associative arrays in PHP:
Method 1: foreach

Copy the code The code is as follows:

$sports = array(
'football' => ' good',
'swimming' => 'very well',
'running' => 'not good');
foreach ($sports as $key => $value) {
echo $key.": ".$value."
";
?>

Copy code The code is as follows:

$sports = array(
'football' => 'good',
'swimming' => 'very well',
'running' => 'not good ');
while ($elem = each($sports)) {
echo $elem['key'].": ".$elem['value']."
";
?> ;

Copy code The code is as follows:

$sports = array(
'football' => 'good',
'swimming' = > 'very well',
'running' => 'not good');
while (list($key, $value) = each($sports)) {
echo $key.": ".$value ."
";
?>
