数组取值,求解
$uc = 33; $wc = getu_province(); foreach ($wc as $k => $v) { $uv=$v['$uc']; $prolist = join('0010'.$uc); foreach ($uv as $s => $a) { if($a[0]=$prolist){ $ucc = $a['$prolist'];} } }
$testArray = array(array('001011' => '北京'), array('001012' => '天津'), array('001013' => '河北'));//$wc = getu_province();$uc = 12;$find = '0010'.$uc;foreach ($testArray as $value) { if (array_key_exists($find,$value)){ echo '地区:' . $value[$find]; break; }}
[解决办法]
$uv=$v['$uc'];
和
$uv=$v["$uc"];
是不一样的。
[解决办法]
$uc=1的话,
"$uc"就是"1",
'$uc'就是字符串"$uc"
因为双引号中,变量名称会被变量值所替代,然后才会发送给浏览器,而单引号就不会这样了。
