Strip out a substring beginning with a specific word and ending with “.”

Tags: , , , ,



From the middle of a text I need to cut out a sentence or better the information about the ingredients of a product. The logic behind is always the same. Starting with “Ingredients” ending with a dot “.”

For example (this is my $prodDesc):

Coca Cola is the most famous soft drink in America.
Ingredients: Carbon water, Sugar (sucrose or high-fructose corn syrup (HFCS) depending on country of origin), Caramel colour (E150d), Phosphoric Acid, Caffeine (34 mg/12 fl oz), natural Flavours. Nutrition Facts: 1 Serving Per Container - Serving Size: 1 Can. Total Fat 0g Sodium 45mg Total Carbohydrate 39g Total Sugars (Includes 39g Added Sugars) Cholesterol 0mg Protein 0g Vitamin D 0g Calcium 0g Iron 0g Potassium 0g

I tried so far with strpros but the fact it is in the middle of the text I get everything from “Ingredients” on until the end.

I need only this as output:

$prodIngredientsData = "Ingredients: Carbon water, Sugar (sucrose or high-fructose corn syrup (HFCS) depending on country of origin), Caramel colour (E150d), Phosphoric Acid, Caffeine (34 mg/12 fl oz), natural Flavours."

Given that $prodDesc is the description above, my try was:

$searchstring = $prodDesc;
$prodIngredientsData = false;
if (strpos($searchstring, "Ingredients") !== false)
{
    $sd_array = explode("Ingredients", $searchstring);
    $sd = end($sd_array);
    $prodIngredientsData = "Ingredients " . $sd;
}
else {
    $prodIngredientsData = false;
}

But as mentioned, I get everything on from “Ingredients” until the end of the description. But it should stop at the first full stop in the example at “Ingredients… …natural Flavours.”

Answer

try with preg_match:

$prodIngredientsData = "Ingredients: Carbon water, Sugar (sucrose or high-fructose corn syrup (HFCS) depending on country of origin), Caramel colour (E150d), Phosphoric Acid, Caffeine (34 mg/12 fl oz), natural Flavours."
preg_match('/(Ingredients:([^.]+))/', $prodIngredientsData, $matches);

echo $matches[0];

Output:

Ingredients: Carbon water, Sugar (sucrose or high-fructose corn syrup (HFCS) depending on country of origin), Caramel colour (E150d), Phosphoric Acid, Caffeine (34 mg/12 fl oz), natural Flavou rs
