    Hi Reader's,
    Welcome to FindNerd, today we are going to discuss What is method to compare two text strings in PHP

    There are two method to check two string In php.

    1: "==" Operator
    2- "strcasecmp() method"

     

    Let explain one by one

    '==': This operator return TRUE, otherwise FALSE and this method is very easy and simple to used for comparing two strings.

    You van see below example :

    Lets take two same string for compare

    Lets take two same string for compare
    <?php
    //define first string
    $str1 = "Hello joy";
    //define second string
    $str2 = "Hello joy";
    //here use '==' operator
    if($str1 == $str2){
    echo "True";
    }else{
    echo "False";
    }
    
    ?>

    Output : True

     'strcasecmp()': This method is Case-insensitive comparison and this is used for comparing two strings.

    strcasecmp() return following value:

     a)  0   - if the two strings are equal
     b) < 0 - if string1 is less than string2
     c) >0  - if string1 is greater than string2

    You can see below example

     let take two string for comparing

    <?php
    
    $str1 = "Hello joy";
    $str2 = "hello joy";
    echo strcasecmp($str1, $str2);
    
    ?>

    Output : 0
