请教:数组元素中的单引号
如下代码:
function method(){
$str = "apply";
$str2 = "tony";
$sql = "select * from table where 1 =1";
$Carray = array(" and cad like '%".$str."%'"," and name like '%".$str2."%'");
//echo($Carray[0]);
for($i=0;$i
}
echo $sql;
}
这段代码是为了简便自己先写的,我想问的是为什么输不出$sql,也就是说输不出数组中的元素,当加上echo($Carray[0]);这一句的时候,是输不出东西的,是不是数组中的单引号出问题了?

没有问题啊。
输出:select * from table where 1 =1 and cad like '%apply%' and name like '%tony%'

function method() { $str = "apply"; $str2 = "tony"; $sql = "select * from table where 1 =1"; $Carray = array(" and cad like '%$str%'", " and name like '%$str2%'"); for ($i = 0; $i <font color="#e78608">------解决方案--------------------</font><br>单引号在双引号的字符串里就做单引号用<div class="clear"> </div>
