问题描述
执行以下操作的最佳方法是什么?
What is the best way to do the following:
我得到一个带有AJAX请求的路径
I get a path with an AJAX request
例如dir1/dir2/dir3/dir4
我需要在我的网页上这样显示它:
I need to present it like this on my webpage:
dir1 >> dir2 >> dir3 >> dir4
每个都是html锚标签,href属性为
each of them being html anchor tags with the href attribute being
/dir1
/dir1/dir2
/dir1/dir2/dir3
/dir1/dir2/dir3/dir4
分别
实现这一目标的最优雅,最有效的方法是什么?
What is the most elegant and efficient way to achieve this?
到目前为止,我正在做这样的事情,我认为它确实很脏:
so far, I'm doing something like this which i think is really dirty:
<?php
$dirs = explode(PATH_SEPARATOR, $this->metadata["path"]);
foreach ($dirs as $key=>$val) {
if ($val == '') {
continue;
}
$pathArray = array();
for ($i = 0; $i <= $key; $i++) {
array_push($pathArray, $dirs[$i]);
}
$path = implode('/', $pathArray);
echo " >> <a href=" . $path . ">" . truncate($val) . "</a>";
}
?>
推荐答案
可能是这样的事情(如果我正确理解了您的意图):
Something like this maybe (if I got your intention right):
<?php
$str = 'dir1/dir2/dir3/dir4';
$output = array();
$chunks = explode('/', $str);
foreach ($chunks as $i => $chunk) {
$output[] = sprintf(
'<a href="#/%s">%s</a>',
implode('/', array_slice($chunks, 0, $i + 1)),
$chunk
);
}
echo implode(' >> ', $output);
输出:
<a href="#/dir1">dir1</a> >>
<a href="#/dir1/dir2">dir2</a> >>
<a href="#/dir1/dir2/dir3">dir3</a> >>
<a href="#/dir1/dir2/dir3/dir4">dir4</a>
