PHP如何实现多维数组转字符串、多维数组转一维数组的方法,php数组与字符串的转换在开发过程中常用到,非常实用,学习PHP的朋友必看。。PHP多维数组转字符串,默认英文逗号（,）作连接符PHP多维数组变成一维数组 $value) {if (is_array($value)){ array_multi2array($value); }else{$result[$key] = $value; }} return $result; } ?>上述方法中用到了PHP的自带函数array_map()函数
PHP递归遍历多维数组的两种方法,实例分析php数组遍历的相关技巧,对数组操作还不熟练的朋友可以参考下\n";}}} } get_array_elems($array); ?>另一个更简洁的array_map()函数递归写法。\n";}}} $array = array(array("1","2","3","4"),array("a","b","c")); each_array($array); ?>

如何把JSON的多维数组转换成JS的多维数组PHP codeJScript code$.getJSON("../php/json.php?parm=arr2", function(json){ //中间应该怎么写 });最终JS的如果是JScript codevar arr1=["a","b","c"];var arr2=[["a1","a2","a3"],["b1","b2","b3"],["c1","c2","c3"]];var arr3=[[["a11","a12","a13"],["a21","a22","a23"],["a31","a32","a33"]],[["b11","b12","b13"],["b21","b22","b23"],["b31","b32","b33"]],[["c11","c12","c13"],[...
多维数组递归问题PHP code//为了实现内容中去除HTML A标签 function htmla(&$string){if(is_array($string)){foreach($string as $k=>$v){$string[$k]=preg_replace("/<\/?a.*?>/","",$v);if(is_array($v)){htmla($string[$k]);}}}else{$string=preg_replace("/<\/?a.*?>/","",$string);}}$test=array(1,2,34,5,array("a"=>"而",1,23,array("df"=>"测试下"),array(23,32)),"b"=>"三");htmla($test);var_dump($test); //结果 array(...
php如何遍历一个复杂的多维数组比如有这样一个数组,毫无规律,怎么遍历?PHP code$arr=array(array(array(val1,val2,val3),aa,bb),php, apache,array(hello,world) );------解决方案-------------------- 你遍历后想做什么？ 可以用递归处理PHP code // 作为回调函数。 参数将不会是数组 function doSomething($value) {echo $value; } function look(array $array) {foreach($array as $value){// 如果仍为数组，则继续遍历if(is_a...
php如何遍历交叉的多维数组并给其id和pid(父键id)PHP codearray(7) {[1] => array(5) {["id"] => string(1) "1"["pid"] => string(1) "0"["name"] => string(15) "AssetManagement"["title"] => string(12) "资产管理"["submenu"] => array(1) {[0] => string(0) ""}}[2] => array(5) {["id"] => string(1) "2"["pid"] => string(1) "0"["name"] => string(14) "SystemSettings"["title"] => string(12) "系统设置"["submenu"] => ...
如何对多维数组的键名进行排序比如$families = array( "Griffin"=>array ( "Peter"=>50 ), "Brown"=>array ( "Cleveland"=>30 ));正序排，排完序后的键名和对应的键值不变，形如下面的形式：$families = array( "Brown"=>array ( "Cleveland"=>30 )，"Griffin"=>array ( "Peter"=>50 ));------解决方案-------------------- PHP code foreach($families as $v) foreach($v as $vl) $p[]=$vl;arr...
多维数组循环读取问题多维数组array( 'a'=>array( 'a2'=>array('dd','ff','gg'), 'a3'=>array('dd','ff','gg') ), 'b'=>array( 'b2'=>array('22','55','88'), 'b3'=>array( 'cs'=>array('nn','mm','xx') ) ))字符串a.a2b.b2b.b3.cs如何根据这个字符串读取相应的数组？比如a.a2 = ['a']['a2'] 结果是 array('dd','ff','gg')b.b2 = ['b']['b2'] 结果是 array('22','55','88')b.b3....
请教：如何将sql查询结果生成多维数组我想实现的功能是这样的：我传递一串数字供sql接收，数字的形式是菜品的ID值，类似“1,2,3，”，经过查询可以变成根据菜品分类而来的多维数组。第一个问题，我如何将这个字符串分离开后循环利用sql查询并保存全部结果呢？PHP code $s=$ids;//接收到的ID字符串 SQL code$sqlslt_veginfo="select {$tb_veg}.veg_id,{$tb_veg}.vsort_id,{$tb_veg}.veg_name,{$tb_veg}.veg_preprice,{$tb_veg}.veg_...
TP session多维数组什么格式？ <?php session_start(); $arr =array(1=>a,2=>b); $arr =array(1=>a,2=>bc); // $_SESSION[list][]=$arr; $_SESSION[list][]=$arr;print_r( $_SESSION[list]);就是存成多维数组，TP下是怎么写的？------解决方案--------------------既然你用 TP 就要按 TP 的规矩来 TP 不是提供了 session 函数用于 session 的读、写、删除操作吗？
数据库查询结果构建多维数组我想将前面数据库查询出来的结果构建一个多维数组，数据库查询出来的第一个结果对应第一层嵌套，第二个结果对应第二层嵌套，如何做，事先声明我是菜鸟，请多指点// 查询变量$sql1 = "select remark,name from arp_careset where typegroup =dissect-position order by id"; $rs1 = mysql_query($sql1); while($r1 = mysql_fetch_assoc($rs1)) { echo $r1[name]; $sql = "select group_concat(name) as ...
多维数组中相同元素相加问题本帖最后由 myths621 于 2013-03-19 12:04:11 编辑首次发帖，请假高手 我从redis中取出五维数组需要处理相加，如下$a = array(0 => array( 0=> array("date" => "201201","area"=> array(12 => array(click => "3",traffic => "30") )), 1=> array("date" => "201202","area"=> array(12 => array(click => "8",traffic => "40"),8=> array(click => "5",traffic => "50"))) ), 1 => array(0=> array("...
PHP多维数组****键名****重命名$a = array(127 => array(0 => dog,1 => cat,2 => duck),854 => array(0 => fish,1 => monkey,2=>bear))请将“127”，“854”重命名成“0”，“1”。不知道是不是有办法，谢谢各位！！！PHPColor分享到：?array(0?=>?dog,1?=>?cat,2?=>?duck),854?=>?array(0?=>?fish,1?=>?monkey..." data-pics="">------解决方案--------------------$a = array_values($a); print_r($a); //看一下
