The before_last_bar() WordPress PHP function is designed to remove the last item from a pipe-delimited string, for instance, ‘Role name|User role’. If no pipe ‘|’ characters are found in the string, the original string will be returned.
Usage
Here’s an example of how to use the function:
$text = "Admin|Editor|Subscriber"; $result = before_last_bar($text); echo $result; // Outputs: "Admin|Editor"
In the example above, the before_last_bar() function is removing ‘Subscriber’ from the string since it is the last item after the last pipe ‘|’.
Parameters
- $text (string) – This is a required parameter, which represents a pipe-delimited string.

Examples
Simple String
$text = "Apple|Banana|Cherry"; echo before_last_bar($text); // This will output: "Apple|Banana"
In this example, ‘Cherry’ is removed from the list of fruits.
String with User Roles
$text = "Administrator|Editor|Author|Contributor"; echo before_last_bar($text); // This will output: "Administrator|Editor|Author"
The ‘Contributor’ role is removed from the user roles string.
String with No Pipe Character
$text = "OnlyOneItem"; echo before_last_bar($text); // This will output: "OnlyOneItem"
As there’s no pipe character in the string, the original string is returned.
Empty String
$text = ""; echo before_last_bar($text); // This will output: ""
An empty string remains empty after the function is called.
String with Multiple Identical Items
$text = "Dog|Dog|Dog|Dog"; echo before_last_bar($text); // This will output: "Dog|Dog|Dog"
Even though all items are identical, the function still removes the last ‘Dog’ from the string.
