PHP/String/strcasecmp

Comparing strings case-insensitively

 
<?
if (strcasecmp("a@demo.ru", "a@demo.ru") == 0) {
    print "Welcome back, Mr..";
}
?>

int strcasecmp ( string str1, string str2 ) is a case-insensitive version of the strcmp( ) .

 
<?
    $result = strcasecmp("Hello", "hello");
?>

strcasecmp() function operates like strcmp(), except that its comparison is case insensitive.

 
Its syntax is: int strcasecmp (string string1, string string2)
<?
$string1 = "butter";
$string2 = "Butter";
if ((strcasecmp($string1, $string2)) == 0) :
     print "Strings are equivalent!";
endif;
?>

Using strcasecmp to compare two strings

 
<?php
$name1 = "Bill";
$name2 = "BILL";
$result = strcasecmp($name1, $name2);
if (!$result){
    echo "They match.";
}
?>
