php实现替换UTF
批量去除BOM的程序
function
replace_utf8bom(
$str
)
{
$charset
[1] =
substr
(
$str
,0,1);
$charset
[2] =
substr
(
$str
,1,1);
$charset
[3] =
substr
(
$str
,2,1);
if
(ord(
$charset
[1]) == 239 && ord(
$charset
[2]) == 187 && ord(
$charset
[3]) == 191)
{
return
substr
(
$str
,3);
}
else
{
return
false;
}
}
很明显，这就是前面三个字符是固定的原因，当然可以这样判断了。。。说白了很简单，但如果不知道就真的很痛苦了。顺便说一下，它来自：http://www.phptext.net/technology.php?vid=53
