使用傳遞的數(shù)組遞歸替換第一個(gè)數(shù)組的元素array_replace_recursive

$base = array('citrus' => array( "orange") , 'berries' => array("blackberry", "raspberry"), );

$replacements = array('citrus' => array('pineapple'), 'berries' => array('blueberry'));

$basket = array_replace_recursive($base, $replacements);

帶索引檢查計(jì)算數(shù)組的交集，用回調(diào)函數(shù)比較索引 array_intersect_uassoc

$array1?=?array("a"?=>?"green",?"b"?=>?"brown",?"c"?=>?"blue",?"red");

$array2?=?array("a"?=>?"GREEN",?"B"?=>?"brown",?"yellow",?"red");

print_r(array_intersect_uassoc($array1,?$array2,?"strcasecmp"));

遞歸地合并一個(gè)或多個(gè)數(shù)組array_merge_recursive

$ar1?=?array("color"?=>?array("favorite"?=>?"red"),?5);\

$ar2?=?array(10,?"color"?=>?array("favorite"?=>?"green",?"blue"));\

$result?=?array_merge_recursive($ar1,?$ar2);

使用傳遞的數(shù)組遞歸替換第一個(gè)數(shù)組的元素 array_replace_recursive

$base?=?array('citrus'?=>?array(?"orange")?,?'berries'?=>?array("blackberry",?"raspberry"),?);

$replacements?=?array('citrus'?=>?array('pineapple'),?'berries'?=>?array('blueberry'));

$basket?=?array_replace_recursive($base,?$replacements);

print_r($basket);\

將一個(gè)線性數(shù)組轉(zhuǎn)換為一個(gè)樹(shù)，或者多維數(shù)組

function array_stack (&$a, $p = '@parent', $c = '@children')

{

$l = $t = array();

foreach ($a AS $key => $val):

if (!$val[$p]) $t[$key] =& $l[$key];

else $l[$val[$p]][$c][$key] =& $l[$key];

$l[$key] = (array)$l[$key] + $val;

endforeach;

return $a = array('tree' => $t, 'leaf' => $l);

}

$node = array();

$node[1] = array('@parent' => 0, 'title' => 'I am node 1.');

$node[2] = array('@parent' => 1, 'title' => 'I am node 2.');

$node[3] = array('@parent' => 2, 'title' => 'I am node 3.');

$node[4] = array('@parent' => 1, 'title' => 'I am node 4.');

$node[5] = array('@parent' => 4, 'title' => 'I am node 5.');

print_r(array_stack($node));
