The strcoll() function compares two strings.
The comparison of the strings may vary depending on the locale settings (A<a or A>a).
int strcoll ( string $str1 , string $str2 )
Note that this comparison is case sensitive, and unlike strcmp() this function is not binary safe.
strcoll() uses the current locale for doing the comparisons. If the current locale is C or POSIX, this function is equivalent to strcmp().
| Parameter | Description |
|---|---|
| string1 | Required. Specifies the first string to compare |
| string2 | Required. Specifies the second string to compare |
Returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal.
