当搜索词在 codeigniter 查询中包含 '(' 时没有结果

Question

I'm trying to search string using CI model. Here is the code written for it.

$test_name = "TSH ( Thyroid stimulating harmone)";
$this->db->like('test_name',$test_name);

Above query when executed gives me zero result. But if I change my database column and replace '(' by '{' or something else then it shows results by executing above code.

new $test_name variable becomes "TSH { T..."}.

But the requirements is to use the string containing '(' only.

How should i carry forward? Please do let me know if additional information is required.

I don't think like() will help you much with your search needs. you use a where() function containing with LIKE clause.

$keyword="TSH ( Thyroid stimulating harmone)"; 

$this->db->select('*')->from('table')->where("column LIKE '%$keyword%'")->get()->result_array();
