Array_diff

[verdrm]

I have two strings:

 

$string = shell_exec('reg.bat '.$arg);  //returns word\0word\0word
$stringA = "$string";
$stringB = "word,other,word2,other2";
$array1 = explode('\0', $stringA);
$array2 = explode(',', $stringB);
$result = array_diff($array1, $array2);

 

I can use array_diff to find the differences, but the last word in $array1 shows up as not in both strings even though it is because of the \0 delimiter. How can I include the last word as well?

perhaps you should add another line

 

$stringA = preg_replace("\0", ',', $stringA);

$array1 = explode(',', $stringA);

$array2 = explode(',', $stringB);

That didn't work. Another suggestion?

hmmm have you echo'd done a print_r on both the $array1 and array2? to see that they are what you need them to be.

 

echo "<pre>";

print_r('ARRAY 1: '.$array1);

print_r('<br>ARRAY 2: '.$array2);

echo "</pre>";

You likely have some other character, such as a space or a \r or \n as part of the data.

 

You should use trim() on each element of the array via the array_map function.

Would you provide a code example of how to do that?
