我正在尝试搜索以确保我们的每个产品标题都包含其制造商代码。我正在使用preg_match，但我得到了一些奇怪的结果。
这是我编写的代码片段，用于浏览产品数组......
while($row = mysql_fetch_array($result))
{
$products[''.$row[0].''][0] = $row[0]; // Product ID
$products[''.$row[0].''][1] = $row[1]; // MFG Part Number
$products[''.$row[0].''][2] = $row[2]; // Product Title
$search_str = $products[''.$row[0].''][1];
$str_to_search = $products[''.$row[0].''][2];
if(preg_match("~" . $search_str . "~i" ,$str_to_search)){
这是它返回的内容......（这是按数组顺序）

因此，由于某些原因，这些都没有加工，看起来括号和星号不匹配。
非常感谢任何帮助我指明正确方向的帮助。
谢谢，
