PHP methods for string operations

This article mainly introduces PHP methods for string operations. Interested friends can refer to it. I hope it will be helpful to everyone.

The example in this article describes how PHP simply determines whether two strings are equal. The specific implementation method is as follows:

Definition and usage

strcasecmp() function compares two strings.

Tip: The strcasecmp() function is binary safe and case-insensitive.

Tip: This function is similar to the strncasecmp() function, except that with strncasecmp() you can specify the number of characters for each string to be compared.

The examples are as follows:

<?php 
function strcomp($str1,$str2){ 
  if($str1 == $str2){ 
    return TRUE; 
  }else{ 
    return FALSE; 
  } 
} 
echo strcomp("First string","Second string");
//Returns FALSE 
echo strcomp("A string","A string");
//Returns TRUE 
?>

Summary: The above is the entire content of this article, I hope it will be helpful to everyone's study.
