php中搜索多维数组的键值程序
例如搜索hok"就会匹配ok里面的数组 "你好,good,很好"打印出来如果搜索"好"没有匹配到第一数组,就会模糊搜索所有含有"好"的的关键词,例如"你好 很好 爱好".
如下面例子,代码如下:
$foo[1]['a']['xx'] = 'bar 1'; $foo[1]['b']['xx'] = 'bar 2'; $foo[2]['a']['bb'] = 'bar 3'; $foo[2]['a']['yy'] = 'bar 4'; $foo[3]['c']['dd'] = 'bar 3'; $foo[3]['f']['gg'] = 'bar 3'; $foo['info'][1] = 'bar 5';
如果要查找 bar 3 怎么进行查找呢,有三个结果,而这三个结果都要,看下面的函数,代码如下:
function array_search_re($needle, $haystack, $a=0, $nodes_temp=array()){ global $nodes_found; $a++; foreach ($haystack as $key1=>$value1) { $nodes_temp[$a] = $key1; if (is_array($value1)){ array_search_re($needle, $value1, $a, $nodes_temp); } else if ($value1 === $needle){ $nodes_found[] = $nodes_temp; } } return $nodes_found; } 这个函数就可以把上面要查找到的内容全部返回出键名来,代码如下: $result = array_search_re('bar 3', $foo); print_r($result); /* 输出结果为如下: Array ( [0] => Array ( [1] => 2 [2] => a [3] => bb ) [1] => Array ( [1] => 3 [2] => c [3] => dd ) [2] => Array ( [1] => 3 [2] => f [3] => gg ) ) */
1,php搜索多维数组的键名,代码如下:
function array_search_key($needle, $haystack){ global $nodes_found; foreach ($haystack as $key1=>$value1) { if ($key1=== $needle){ $nodes_found[] = $value1; } if (is_array($value1)){ array_search_key($needle, $value1); } } return $nodes_found; } $result = array_search_key('a', $foo); print_r($result); /* 输出结果为如下: Array ( [0] => Array ( [xx] => bar 1 ) [1] => Array ( [bb] => bar 3 ) [2] => Array ( [yy] => bar 4 ) ) */
类似全文匹配,用二个循环,第一个循环keys,第二个模糊匹配,用函数strstr() 来解决.
