In PHP, arrays are divided into two categories: numeric indexed arrays and associative arrays.
Where the numeric index array is the same as the array in the C language, the subscript is for 0,1,2 ...
Associative array subscripts may be of any type, similar to Hash,map in other languages.
Here are three ways to traverse associative arrays in PHP:
Method 1:foreach

Copy the Code code as follows:


$sports = Array (
' Football ' = ' good ',
' Swimming ' = ' very well ',
' Running ' = ' not good ');
foreach ($sports as $key = = $value) {
echo $key. ":". $value. "
";
?>


Output Result:
Football:good
Swimming:very Well
Running:not Good
Method 2:each

Copy the Code code as follows:


$sports = Array (
' Football ' = ' good ',
' Swimming ' = ' very well ',
' Running ' = ' not good ');
while ($elem = each ($sports)) {
echo $elem [' key ']. ":". $elem [' value ']. "
";
?>


Method 3:list & each

Copy the Code code as follows:


$sports = Array (
' Football ' = ' good ',
' Swimming ' = ' very well ',
' Running ' = ' not good ');
while (list ($key, $value) = each ($sports)) {
echo $key. ":". $value. "
";
?>
