PHP程序两个字符串的串联
要在PHP中连接两个字符串，代码如下-
示例
<?php
$a = 1.967;
$b = 1.969;
$res = $a." and ".$b;
echo " $res \n";
if((round($a, 2)) == (round($b, 2))) {
echo "\nBoth the values are equal!";
} else {
echo "\nBoth the values aren\'t equal";
}
?>输出结果
1.967 and 1.969 Both the values are equal!
示例
现在让我们来看另一个示例-
<?php $val1 = 'Jack'; $val2 = 'Sparrow'; echo "First Name = $val1 \n"; echo "Second Name = $val2 \n"; $res = $val1.$val2; echo "Concatenation = $res \n"; ?>
输出结果
First Name = Jack Second Name = Sparrow Concatenation = JackSparrow
