php中搜索多维数组的键值程序
例如搜索“ok”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.
