my English is not good. sorry.
I want echo post_12345678 from my URL sting:
always want to echo the One thing before the end.
<?php
$url_string = "https://localhost/categories/post_12345678/a25d48aff";
echo preg_replace('/[\^categories/].*?[\/]/' , '', $string );
?>
- a25d48aff and post_12345678 is Variable
>Solution :
With parse_url, this task becomes much simpler. Just extract the value of the path key and access the second last key using explode and array_reverse.
<?php
$url_string = "https://localhost/categories/post_12345678/a25d48aff";
$str = trim(parse_url($url_string)['path'], '/');
echo array_reverse(explode("/", $str))[1];
