$stringA = “hello world hello world helloo world”;
$stringB = “hello php hello php hello php”;

echo “string 1—->”.$stringA.”";
echo “string 2—->”.$stringB.”";

$array1 = explode(‘ ‘, $stringA);
$array2 = explode(‘ ‘, $stringB);

$result = array_diff($array2, $array1);

$zem= implode(‘ ‘,$result);
if (!empty($zem)) {

echo “string diffrence—> “.$zem.”";

}
else {
echo “string diffrence—>both strings are same “;
}

But Text_Diff has many warnings in PHP5

Hmm... it appears this comment box strips tags, including my PHP example. Here it is again, without PHP tags.

include_once 'inline_function.php';
$nl = '#**!)@#';
$a = '1 1';
$b = '1 2';
ob_start();
inline_diff($a, $b, $nl);
$differences = ob_get_contents();
ob_end_clean();

// $differences now contains the result, and nothing has been output to the browser.

lenselijer,

I’ve got the same problem as you (it echoes before going to variable and the variable is then empty).
Did you find a solution ? If so, what was it ?

Thx !

For me there’s nothing shown on screen. I copy/pasted my code where I use it. I don’t know where is your problem.

When I use:

include_once ‘inline_function.php’;
$nl = ‘#**!)@#’;
$a = ’1 1′;
$b = ’1 2′;
$differences = inline_diff($a, $b, $nl);

The output of $differences is already shown on the screen, and i dont put echo before it. Can it save the output to the variable instead?.

I want to use $differences later on in my php code by using:
$message = str_replace(‘{content}’, $differences, $message);
echo $message;

Is this possible? I think it has something to do with echo “$line “; in inline_renderer.php.

I hope you can help me.

include_once 'inline_function.php'; $nl = '#**!)@#'; $text_with_marked_differences = inline_diff($original_text, $modified_text, $nl);
