PHP strcmp Function
What is strcmp Function and how it is used in string?
Explanation
In PHP, this function is used to compare two strings and is case sensitive.
Syntax:
strcmp(string1,string2)
In the above syntax "string1", "string2" specifies the strings to be compared, the function returns "0" if both strings are equal, returns a value ">0" if "string1" is greater than "string2", returns a value "<0" if "string1" is less than "string2".
Example :
<?php
$s1="Hello World";
$s2="hello world";
echo strcmp($s1,$s2);
echo "<br>";
if(strcmp($s1,$s2)==0)
{
echo "Two strings are matching";
}
else
{
echo "Two strings are different";
}
?>
Result :
-1
Two strings are different
In the above string example if we have used strcasecmp(), it will give a result "0",ie., both strings are equal, but when used strcmp() as its case sensitive it gives a result "-1",ie., "string1" is less than "string2".
