子串提取。 在前一个'/'之前获取字符串

Question

I am trying to extract a sub-string. I need some help with doing it in PHP.

Here are some sample strings I am working with and the results I need:

$temp = "COM1904150001","1","ytuaioeighalk","tyueiff","assets/report/celc_coba/d02c25b2-5c07-11e9-8f1a-02fd8bf7d052/"

And the result i need is:

$temp = d02c25b2-5c07-11e9-8f1a-02fd8bf7d052

I want to get the string at my last '/'

So far, I've tried:

substr($temp, 0, strpos($temp, '/'))

But, it seems didn't work at all.

Is there a way to handle that case with PHP approach ?

Answer 1

You can use substr() to extract the data, but using strrpos() instead to find the last / position (you have to remove the trailing / to do this though)

$temp = "assets/report/celc_coba/d02c25b2-5c07-11e9-8f1a-02fd8bf7d052/";
// Trim off trailing / or "
$temp = rtrim($temp, "/\"");
// Return from the position of the last / (+1) to the end of the string
$temp = substr($temp, strrpos($temp, '/')+1);
echo $temp;

gives...

d02c25b2-5c07-11e9-8f1a-02fd8bf7d052
