It is necessary that it turned out:

 bd217ce34263e9bf8679562067758196.xls|17fc9e435a3d3a1d1e6f12c13fe1262f.xls|42be09853a529555d6f2316f1f29b593.xls

The str_replace function str_replace not work, because after 3 slashes, the parameters change all the time.

Tried the strrchr function

 $param = "/download/doc/bd2/bd217ce34263e9bf8679562067758196.xls|/download/doc/17f/17fc9e435a3d3a1d1e6f12c13fe1262f.xls|/download/doc/42b/42be09853a529555d6f2316f1f29b593.xls "; $string = substr(strrchr($param, "/"), 1); echo $string;

But she only returns 42be09853a529555d6f2316f1f29b593.xls

  • Split string by '|' and use pathinfo . - Yaant

For example, so

 $result = preg_replace('~/[\w/]*/~', "", $str);

either so

 $result = []; foreach(explode('|', $str) as $file){ $result[] = basename($file); } $str = implode("|", $result);

what can be written as

 $str = implode("|", array_map('basename', explode("|", $str)));
