Remove values with digit only from array - PHP

arrays, digits, php

Solution

$data = array( 1 => "hello", 
               2 => "foo", 
               3 => "192", 
               4 => "keep characters AND digits like a1e2r5", 
             );

$result = array_filter( $data, 
                        function($arrayEntry) { 
                            return !is_numeric($arrayEntry);
                        }
                      );

Or using slightly more modern PHP, with arrow functions:

$result = array_filter( $data, 
                        fn($arrayEntry) => !is_numeric($arrayEntry)
                      );

Problem

I have an array like so ``` array( 1=>hello, 2=>foo, 3=>192, 4=>keep characters AND digits like a1e2r5, ); ``` All I want to do is to remove rows containing digits ONLY `(3=>192)`, and return an array like this one : ``` array( 1=>hello, 2=>foo, 3=>keep characters AND digits like a1e2r5, ); ``` I tried with array_filter but didn't get it work. Can someone show me how to do? Thanks
