| 变量 | 弱类型语言，变量可以任意代表任何类型 $age = 13; $name = "pengpeng"; $money = 150.53; $isBoy = true; 这里等号前后空格是为了整齐好看。 例子 <?php $age = 13; print $age; ?> 运行方式 php t.php |
弱类型语言 age=13 name="pengpeng" money=150.53 isBoy=true 注意：这里等号前后不能空格，shell的语法规则导致。 再次调用变量的时候需要加$ 符号。 例子 #!/bin/bash
age=13
echo $age
运行方式
sh t.sh
shell的逻辑变量样例
#!/bin/bash
test1=true
if $test1 ; then
echo "ok";
fi
test2=false;
if $test2 ; then
echo "false";
fi
|
弱类型语言 my $age = 13; my $name = "pengpeng"; my $money = 150.53; my $isBoy = true; 例子 #! /usr/bin/perl my $age = 13;
print $age;
运行方式

下划线表示匹配任意字符
例
mysql> select * from student where name like‘_____‘;
假如我们要查找的名字包括5个字母，我们就可以使用特殊的字母"_"（下划线）。将列好在表student中包括5个字母学生的名字
例

0_1_2
0_1_2_3
0_1_4
0_1_6
