小弟就是想问问，能不能这样写php代码啊？true和flase用不来。
$abc=4/2;
if($abc=2){
echo $abc=true;
else{
echo $abc=false;;
?>
回复讨论(解决方案)
<html><head></head><title>梁静茹</title><body><?php$abc=4/2;if($abc=2)echo $abc=true;elseecho $abc=false;;?></html>
为什么不打括号呢？java语言都要在if里面打括号啊
<html><head></head><title>梁静茹</title><body><?php$abc=4/2;if($abc=2){ echo $abc=true;}else{ echo $abc=false;}?></html> 楼主啊，单等号是赋值，不是判断啊
你在if里面把$abc赋值为2，非零，为真，else没有意义了
echo 后面的也应该换成双等号来判断是否相等
此时$abc的值为2 $abc == true 的结果是1
前题是 你把文件保存成 .php 格式！
$abc = 4/2;
if($abc == 2)
echo $abc = true;
else
echo $abc = false;;
?>
if($abc =2)
“=” 是赋值 不是比较
= 赋值 == 比较内容 === 比较地址与内容
if($abc=2){ // $abc==2
