php数组填充

[qq_34921650]

$arr=array ('0' => array ( 'num' => '8','search_name' => '好' ),'1' => Array ( 'num' => '8', 'search_name' => '奇迹' ), '2' => Array ( 'num' => '6' ,'search_name' => '奇' ) ,'3' => Array ( 'num' => '6', 'search_name' => '奇迹哥' ) ,'4' => Array ( 'num' => '1', 'search_name' => '不好' ), '5' => Array ( 'num' => '6' ,'search_name' => '到底' ), '6' => Array ( 'num' => '5', 'search_name' => '孪' ),'7' => Array ( 'num' => '5' ,'search_name' => '结果' ) ,'8' => Array ( 'num' => '5', 'search_name' => '你好' ) );

数组如上：num理解为点击数 search_name点击的标签名称 把点击量一样的标签合并成字符串
结果为

$arr=array (

	'0' => array ( 'num' => '1','search_name' => '不好' ),
	'1' => Array ( 'num' => '2', 'search_name' => '无' ),
	'2' => Array ( 'num' => '3' ,'search_name' => '无' ) ,
	'3' => Array ( 'num' => '4', 'search_name' => '无' ) ,
	'4' => Array ( 'num' => '5', 'search_name' => '孪,结果,你好' ), 
	'5' => Array ( 'num' => '6' ,'search_name' => '到底,奇迹哥,奇' ), 
	'6' => Array ( 'num' => '7', 'search_name' => '无' ),
	'7' => Array ( 'num' => '8' ,'search_name' => '好,奇迹' ) 
	);

谢谢版主 不过就是填充数组时候那个num的值能不能变成题目中要求的那个值呢 ?

[xuzuning]

可以呀，但那样并不合情理

恩 我就是想问一下怎么填充进去 实际操作中有版主你这个填充就可以的

[xuzuning]

foreach($res as $k=>$v) $res[$k]['num'] = $k;

$arr=array ('0' => array ( 'num' => '8','search_name' => '好' ),'1' => Array ( 'num' => '8', 'search_name' => '奇迹' ), '2' => Array ( 'num' => '6' ,'search_name' => '奇' ) ,'3' => Array ( 'num' => '6', 'search_name' => '奇迹哥' ) ,'4' => Array ( 'num' => '1', 'search_name' => '不好' ), '5' => Array ( 'num' => '6' ,'search_name' => '到底' ), '6' => Array ( 'num' => '5', 'search_name' => '孪' ),'7' => Array ( 'num' => '5' ,'search_name' => '结果' ) ,'8' => Array ( 'num' => '5', 'search_name' => '你好' ) );

$max = 0;
