例如搜索“ok”就會匹配ok里面的數組 “你好,good,很好/"打印出來如果搜索“好”沒有匹配到第一數組,就會模糊搜索所有含有“好”的的關鍵詞,例如“你好 很好 愛好”.
如下面例子,代碼如下:
- $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';
- $foo['info'][1] = 'bar 5';
如果要查找 bar 3 怎么進行查找呢,有三個結果,而這三個結果都要,看下面的函數,代碼如下:
- function array_search_re($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;
- }
這個函數就可以把上面要查找到的內容全部返回出鍵名來,代碼如下:
- $result = array_search_re('bar 3', $foo);
- print_r($result);
- /*
- 輸出結果為如下:
- 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搜索多維數組的鍵名,代碼如下:
- 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);
- /*
- 輸出結果為如下:
- Array
- (
- [0] => Array
- (
- [xx] => bar 1
- )
- [1] => Array
- (
- [bb] => bar 3
- )
- [2] => Array
- (
- [yy] => bar 4
- )
- )
- */
類似全文匹配,用二個循環,第一個循環keys,第二個模糊匹配,用函數strstr() 來解決.
