被 HTML 实体替换的字符重新出现
我在执行简单的 str_replace 时遇到问题。
我正在尝试从字符串中删除所有逗号，这确实有效。但是当我尝试再次更改字符串时，逗号以某种方式重新出现。我重构了我的代码以确保这不是我造成的。
无论如何，这是我的代码。有人能发现错误吗？
$delim=remDelim(fgets($fo));
# echo 'before : '.htmlspecialchars($delim);
$delime =str_replace(",",",",$delim);
echo 'after : '.htmlspecialchars($delime);
$delimed = str_replace("<","",$delime);
echo $delimed.'<br />';
example output:
Jose, jr to Jose, jr to Jose, jr
就像我的字符串没有被转换一样。我想说，很可能是我把名字搞混了，用第一个字符串来制作最后一个字符串。但可惜我发现事实并非如此。
I am having trouble doing a simple str_replace.
I am trying to remove all comma's from a string, which does work. But when I try to alter the string again, the commas reappear somehow. I refactored my code to ensure I didn't cause this.
Anyways here is my code. Can anybody spot a bug?
$delim=remDelim(fgets($fo));
# echo 'before : '.htmlspecialchars($delim);
$delime =str_replace(",",",",$delim);
echo 'after : '.htmlspecialchars($delime);
$delimed = str_replace("<","",$delime);
echo $delimed.'<br />';
example output:
Jose, jr to Jose, jr to Jose, jr
Its like my string is being unconverted somehow. I would say that it was most likely I got the names mixed up and used the first string to craft the last. But alas I can see that is not the case.
