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
