The strcoll() is an inbuilt function in PHP and is used to compare two strings. This function is case-sensitive which points that capital and small cases will be treated differently, during a comparison. This function compares two strings and tells us that whether the first string is greater or smaller than the second string or equals to the second string.
Parameters:The function accepts two mandatory string parameters which are described below.
- $string1: This parameter refers to the first string to be used in the comparison.
- $string2: This parameter refers to the second string to be used in the comparison.
Return Value: The function returns a random integer value depending on the condition of match, which is given by:
- Returns 0 if the strings are equal.
- Returns a negative value (<0), if $string1 is lesser than $string2.
- Returns a positive value (>0) if $string2 is lesser than $string1.
Input : $string1 = "geeks for geeks" $string2="geeks for geeks" Output : 0 Input : $string1 = "striver" $string2="raj" Output : 1
