请问php代码间的跳转函数有没有不是页面间的跳转
请问php代码间的跳转函数有没有??不是页面间的跳转
比如:
$str="";
$a=array(1,2,3,4,5,6);
$b=array(1,4,3,4,5,6);
$i=0;
foreach($a as $value){
if($a[$i] //如果条件满足,退出循环,直接执行最后的输出"数据有问题 ";
}else{
$str="aaaa=".$a[$i];
}
$i++;
}
echo "数据有问题";
回复讨论(解决方案)
break;
...if($a[$i]<$b[$i]){ echo "数据有问题";//如果条件满足,退出循环,直接执行最后的输出"数据有问题 "; exit(); }...
可能我的示例没有表达出我的情况
if(){//前面还有很多个这样的,以下代码在很多个if里面$str=""; $a=array(1,2,3,4,5,6);$b=array(1,4,3,4,5,6);$i=0;foreach($a as $value){ if($a[$i]<$b[$i]){ //如果条件满足,退出循环,直接执行最后的输出"数据有问题 "; }else{ $str="aaaa=".$a[$i]; }$i++;} //这中间还有很多代码,我就是不要执行这部分代码 echo "数据有问题";
if($condition){
die("数据有问题");
}
//正确用法是if(成立) { 做点什么} else { 做点其他的}//你的用法是if(成立) { 去做点什么} else { 做点其他的}{不想做的东西}{要做的东西}
$str=""; $a=array(1,2,3,4,5,6);$b=array(1,4,3,4,5,6);$i=0;foreach($a as $value){ if($a[$i]<$b[$i]){ xiangzuode();//如果条件满足调用想做的; break;//做完了要退出! }else{ $str="aaaa=".$a[$i]; }$i++;} function buzuode() { //不想做的,什么时候想做什么时候调用} function xiangzuode() {//想做的 echo "数据有问题";}
