How does PHP compare the size of a string?

In WEB project development, we often need to determine the size between two or more strings.

In WEB project development, we often need to determine the size between two or more strings.

First, we should first learn two functions.Strcmp () and strcasecmp () functions

Both functions are used to compare the sizes of two strings. their syntax is as follows:

strcmp(str1,str2)

strcasecmp(str1,str2)

These two functions compare the size of two strings based on the (ASCII code value). if str1> str2, 1 is returned; if str1

Application instance

The following uses the strcasecmp () and strcmp () functions to compare the string size.

The code is as follows:

    
     String case-sensitive conversion
 String '". $ str1."'> string '". $ str2 ."'
";} If ($ result = 0) {echo"
String '". $ str1."' = String '". $ str2 ."'
";} If ($ result =-1) {echo"
String '". $ str1."' <string '". $ str2 ."'
";}}?>
