Retrieve two strings from one

I need to get two strings from one.

$string = "Service rating : good<br/>Product : good";

should return:

$service = 'good';
$product = 'good';

and

$string = "Service rating : Excellent service!<br/>Product : Outstanding product - this is the second scarf I've ordered.";

should return:

$service = 'Excellent service!';
$product = 'Outstanding product - this is the second scarf I've ordered.';

How can I best achieve this?

Just an alternative using preg_match_all():

Basically:

  • ([a-zA-Z\s]+) : ([a-zA-Z\s-\']+) Search for a group of words with the allowed chars inside the square brackets, with a semicolon between them.

You can then apply your logic to handle the resulting array. 

$string1 = "Service rating : good<br/>Product : good";

$string2 = "Service rating : Excellent service!<br/>Product : Outstanding product - this is the second scarf I've ordered.";


function getRate($string) {
    preg_match_all('#([a-zA-Z\s]+?) : ([a-zA-Z\s-\']+)#', $string, $matches, PREG_SET_ORDER);

    return $matches ?: false;
}

var_dump(getRate($string1));


var_dump(getRate($string2));

You can separate the string using the explode function 2 times. First - to separate the service from product using the tag <br/> in the middle. The second use will get the corresponding status - using explode with the string " : "

Here is the code

<?php
$input = "Service rating : good<br/>Product : good";
list($service, $product) = explode('<br/>', $input);

$service = explode(' : ', $service);
$product = explode(' : ', $product);
echo $service[1];
echo "<br>";
echo $product[1];
?>

You could use regular expressions for your solution. I give an example:

$string = "Service rating : good<br/>Product : good";
$re = '/^.*\:\s*(?:(?<service>[\w\s]+)\<br\/>).*\:\s*(?<product>[\w\s]+)$/';

if (preg_match($re, $string, $matches))
{
    $service = $matches['service'];
    $product = $matches['product'];
}

var_dump($service, $product);

Explanation of the used expression:

  • skip everything from beginning until 1st :
  • extract service match delimited by <br/>
  • skip everything until 2nd :
  • extract product match (until end of string)

$a = explode("<br/>", $string);

will provide you with an array with two values: the strings you ask for.

Then:

echo $a[0];
echo $a[1];

will print the two strings.

Or use list to assign those values to your requested variables:

list($service, $product) = explode("<br/>", $string);

Then, as bladerz suggests, repeat the explode with ' : ' for getting the ratings for service and product.
