A quick and simple way to search a MySQL database.
示例:
mysqlsearch('items', 'title tags', isset($GET['q'])?$GET['q']:'', Array('columns'=>'*', 'method'=>'OR', 'extrasql'=>'AND active = "true" ORDER BY id DESC'));
- if (!function_exists('mysql_search')) {
- function mysql_search($table, $columns, $query = '', $options = Array()) {
- if (empty($query)) { return Array(); }
- $sql_query = Array();
- $options['columns'] = isset($options['columns'])?$options['columns']:'*';
- $options['method'] = isset($options['method'])?$options['method']:'OR';
- $options['extra_sql'] = isset($options['extra_sql'])?$options['extra_sql']:'';
- $query = ereg_replace('[[:<:]](and|or|the)[[:>:]]', '', $query);
- $query = ereg_replace(' +', ' ', trim(stripslashes($query)));
- $pattern = '/([[:alpha:]:]+)([[:alpha:] ]+)[[:alpha:]]?+[ ]?/i';
- $regs = Array();
- preg_match_all($pattern, $query, $regs);
- $query = $regs[0];
- while (list($key, $value) = @each($query)) {
- $column = $columns;
- $keywords = urldecode($value);
- if (strpos($value, ':')) {
- $column = substr($value, 0, strpos($value, ':'));
- $keywords = trim(substr($keywords, strpos($keywords, ':') + 1));
- $keywords = ereg_replace('\'', '', $keywords);
- } else { $keywords = ereg_replace(' +', '|', $keywords); }
- $column_list = explode(' ', $column);
- $sql = Array();
- for ($i = 0; $i < count($column_list); $i++) { $sql[] = '' . $column_list[$i] . ' REGEXP "' . $keywords . '"'; }
- $query[$key] = Array('orignal'=>$value, 'sql'=>implode(' ' . $options['method'] . ' ', $sql));
- $sql_query = array_merge($sql_query, $sql);
- $sql_query = implode(' ' . $options['method'] . ' ', $sql_query);
- }
- $results = mysql_fetch_results(mysql_query('SELECT ' . $options['columns'] . ' FROM ' . $table . ' WHERE ' . $sql_query . ' ' . $options['extra_sql']));
- return $results;
- }
- }
