trim (ltrim) 削减更多

Question

我有很多产品名称和品牌。一些产品名称包含品牌。有些没有。 我想删除产品名称中的品牌。 substr($name,strlen($brand)); 导致无品牌名称出现问题。

然后我使用这个代码。但又出问题了。

$brand = "Palm See";

$name = "Palm See Second Third ... "; 
$name = "See Season ... ";
$name = " See Sean Paul ";

$name = ltrim($name, $brand);

echo $name;     // cond Third ...   desired : Second Third ...
echo $name;     // son ...          desired : See Season ...
echo $name;     // n Paul           desired : See Sean Paul

Answer 1

再看看 ltrim 的工作原理：

character_mask

You can also specify the characters you want to strip, by means of the character_mask parameter. Simply list all characters that you want to be stripped. With .. you can specify a range of characters.

尝试使用 str_replace 将其删除，仅使用 trim 删除任何多余的空格。
