Apology for the confuse, the line different due to I remove the 3 lines 'echo', I did not notice it.
I tried your code works fine in Solaris and SUSE! Your code is so neat
May I know what is the meaning for below coding?
I found my logic mistake and changed as below yesterday (divide result from 1min CPU LOAD with 5mins and 15mins, if it is less than 1.03 (3%) then it is normal, if more than 1.03 (3) then is warning, if more than 1.05 (5%) it is critical.).
1 min load 3% < 5mins and 15mins is normal
1 min load 3% > 5mins or 15mins is warning
1 min load 5% > 5mins or 15mins is critical

LEVENSHTEIN(3) 1 LEVENSHTEIN(3)levenshtein - Calculate Levenshtein distance between two stringsSYNOPSIS
int levenshtein (string $str1, string $str2)
DESCRIPTION
int levenshtein (string $str1, string $str2, int $cost_ins, int $cost_rep, int $cost_del)
The Levenshtein distance is defined as the minimal number of characters you have to replace, insert or delete to transform $str1 into
$str2. The complexity of the algorithm is O(m*n), where n and m are the length of $str1 and $str2 (rather good when compared to simi-
lar_text(3), which is O(max(n,m)**3), but still expensive).
In its simplest form the function will take only the two strings as parameter and will calculate just the number of insert, replace and
delete operations needed to transform $str1 into $str2.
A second variant will take three additional parameters that define the cost of insert, replace and delete operations. This is more general
and adaptive than variant one, but not as efficient.
PARAMETERS
o $str1
- One of the strings being evaluated for Levenshtein distance.
o $str2
- One of the strings being evaluated for Levenshtein distance.
o $cost_ins
- Defines the cost of insertion.
o $cost_rep
- Defines the cost of replacement.
o $cost_del
- Defines the cost of deletion.
RETURN VALUES
This function returns the Levenshtein-Distance between the two argument strings or -1, if one of the argument strings is longer than the
limit of 255 characters.
EXAMPLES
Example #1
levenshtein(3) example
<?php
// input misspelled word
$input = 'carrrot';
// array of words to check against
$words = array('apple','pineapple','banana','orange',
'radish','carrot','pea','bean','potato');
// no shortest distance found, yet
$shortest = -1;
// loop through words to find the closest
foreach ($words as $word) {
// calculate the distance between the input word,
// and the current word
$lev = levenshtein($input, $word);
// check for an exact match
if ($lev == 0) {
// closest word is this one (exact match)
$closest = $word;
$shortest = 0;
// break out of the loop; we've found an exact match
break;
}
// if this distance is less than the next found shortest
// distance, OR if a next shortest word has not yet been found
if ($lev <= $shortest || $shortest < 0) {
// set the closest match, and shortest distance
$closest = $word;
$shortest = $lev;
}
}
echo "Input word: $input
";
if ($shortest == 0) {
echo "Exact match found: $closest
";
} else {
echo "Did you mean: $closest?
";
}
?>
The above example will output:
Input word: carrrot
Did you mean: carrot?
