how find the difference in string vars? 1

[AlbertAguirre]

$basestr="this is a test of the emergency broadcast system"
$otherstrg="this is not a test of the urgent broadcast system"

I just want to compare $otherstr to the $basestr, not the other way around.

The difference in $otherstr is:
"not" and "urgent"

possible?

You could use eregi() looking for specific terms
then use preg_replace() to modif the str

 

[AlbertAguirre]

Differences would be random. Would not know what to search for.
Dont want to modify just identify differences.

 

[webdev007]

Is there anything fixed?
if so read str, search and rem the known segments.
the left should be = to rand

 

[AlbertAguirre]

Nothing fixed. Its a device configuration file.

found a solution though:

Its equivalent to a unix diff

it may be possible to use array_diff to do what you need as well

<?
$string1 = "The quick brown fox jumps over the lazy black dog";
$string2 = "The quick brown chicken jumps over lazy black dog";

$a1 = explode (" ", $string1);
$a2 = explode (" ", $string2);

$result = array_diff($a1, $a2);

print_r ($result);
?>
