How to stop the loop of php foreach?

Foreach jumps out of this/current loop and terminates the loop method

In the foreach() loop, you want to jump out of this loop when a certain condition is met. Continue to execute the next loop, or terminate the foreach() loop when a certain condition is met. You will use: continue and break respectively

PHP:

 foreach($arras $key => $value){  
    if($value=='b'){
        $html.= $value;  
        continue;// 当 $value为b时，跳出本次循环  
    }  
    if($value=='c'){  
        $html.= $value;  
        break;// 当 $value为c时，终止循环  
    }
}
echo$html; // 输出： abc

JavaScript:

var myerror = null;  
             try{  
                 arr.forEach(function(el,index){  
                     if (el==20) {  
                         console.log("try中遇到20,能退出吗?");//  
                         foreach.break=new Error("StopIteration");  
                     }else{  
                         console.log(el);  
                     }  
                 });  
             }catch(e){  
                 console.log(e.message);  
                 if(e.message==="foreach is not defined") {  
                     console.log("跳出来了?");//  
                     return;  
                 }else throw e;  
             }//可以跳出来
