php语法中有哪些遍历数组方法

php语法中有哪些遍历数组方法，下面编程教程网小编给大家介绍php遍历的五种方法！

利用array_map()函数遍历

$arr = ["香蕉","苹果","梨子","橙子","橘子","榴莲"];
var_dump($arr);
$arr = array_map(function ($item) {
  return $item . '_i';
}, $arr);
var_dump($arr);

利用array_walk()函数遍历

$arr = ["香蕉","苹果","梨子","橙子","橘子","榴莲"];
array_walk($arr, function (&$item) {
  $item = $item . '_i';
});
var_dump($arr);

利用for循环遍历

header("Content-type:text/html;charset=utf-8");
$array= array("香蕉","苹果","梨子","橙子","橘子","榴莲");
for ($i=0; $i < count($array); $i++) { 
  echo $array[$i] . "<br/>";
} 

利用foreach循环遍历

header("Content-type:text/html;charset=utf-8");
$array= array("香蕉","苹果","梨子","橙子","橘子","榴莲");
foreach ($array as $val){
  echo "值是：" . $val ;
  echo "<br/>";
}
echo "<br/>";
foreach ($array as $key => $value) { 
  echo "键名为：".$key."，键值为：".$value . "<br/>";
} 

利用while循环+each()+list()遍历

header("Content-type:text/html;charset=utf-8");
$array= array("香蕉","苹果","梨子","橙子","橘子","榴莲");
while( list($key, $val) = each($array) ) {
  echo "$key => $val<br>";
}
