array_map:

echo implode(', ', array_map(function ($entry) {
	$shoes = array($entry[3], $entry[1]);
	$shoes_string = implode(' ', $shoes);
	return $shoes_string;
}, $row_product));
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
    

The last example will display all models of shoes - male or female, you can also display the color and all other values ​​from the $ product array.

If you need to get only one value from $ row_product, you can use the array_column function:

echo implode('', array_column($row_product, 3));
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
    

Thus, the php implode function provides access to many of the array features that are useful for getting data and manipulating output lines, which frees us from a strict string concatenation sequence.
