Question

I have a variable on my page called, $recipe['ingredients'];

inside the var you have as follows,

100ml milk, 350ml double cream, 150ml water

and so on. Now I’m trying to split it up so it looks as follows

<ul>
    <li>100ml milk</li>
    <li>350ml double cream</li>
    <li>150ml water</li>
</ul>

So far I have the following code,

$ingredientsParts = explode(',', $row_rs_recipes['ingredients']);
$ingredients = array($ingredientsParts);
while (! $ingredients) { 
   echo" <li>$ingredients</li>";
}

But for some reason it doesn’t work and I do not have the experience with explode to fix it.

Answer 1

1. When you explode() a string it is automatically converted into an array. You do not need to convert it to an array type as you did on the second line.

2. You want to use a foreach() loop to iterate through an array, not a while loop.

      $ingredientsAry = explode(',', $row_rs_recipes['ingredients']);
      foreach($ingredientsAry as $ingredient){
          echo "<li>$ingredient</li>";
      }
   

In fact you can just do a foreach() loop on the explode() value

foreach(explode(',', $row_rs_recipes['ingredients']) as $ingredient){
    echo "<li>$ingredient</li>";
}
