高版本PHP环境(7.3+)下安装phpcms报continue语法错误处理方法
Views / 收藏到本站 / 收藏到浏览器问题描述：
如图，在安装的最后一步报：
Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"
解决方法：
用编辑器打开：\phpcms\libs\classes\db_mysqli.class.php 文件，将245行和254行的continue；改为continue 2；
foreach($data as $k=>$v) {
switch (substr($v, 0, 2)) {
case '+=':
$v = substr($v,2);
if (is_numeric($v)) {
$fields[] = $this->add_special_char($k).'='.$this->add_special_char($k).'+'.$this->escape_string($v, '', false);
} else {
continue 2;
}
break;
case '-=':
$v = substr($v,2);
if (is_numeric($v)) {
$fields[] = $this->add_special_char($k).'='.$this->add_special_char($k).'-'.$this->escape_string($v, '', false);
} else {
continue 2;
}
break;
default:
$fields[] = $this->add_special_char($k).'='.$this->escape_string($v);
}
}
