在 PHP 中使用 == 運算子和 STRCMP 函式進行字串比較

<?php

// Our Currencies
$value1 = "USD";
$value2 = "EUR";
// Use the == to compare our currencies
if ($value1 == $value2) {
	echo 'The Currencies are the same';
}
else {
	
	echo 'The Currencies are not the same;
}
?>

The Currencies are not the same

<?php
// Our variable with an Integer value
$value1 = 290;
// Our variable with a String value
$value2 = "290";
// Compare $value1 with value2 using the == operator
if ($value1 == $value2) {
	echo 'The values are the same';
}
else {
	
	echo 'The values are not the same;
}
?>

The values are the same

<?php
// Our variable with an Integer value
$value1 = 290;
// Our variable with a String value
$value2 = "290";
// Compare $value1 with value2 using the === operator
if ($value1 === $value2) {
	echo 'The values are the same';
}
else {
	
	echo 'The values are not the same;
}
?>

The values are not the same

<?php
echo strcmp("Joyce","Joyce")."<br>"; // (Equal strings) First name with First name

echo strcmp("Joyce Lynn", "Joyce")."<br>"; // String1 greater than string2

echo strcmp("Joyce", "Joyce Lynn Lee")."<br>"; // String1 less than String 2

 ?>
