Is there a jump function between PHP code that is not a jump between pages

Is there a jump function between PHP code? Not a jump between pages

Like what:

$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]) {
If the condition satisfies, exits the loop, executes the final output directly "the data has the problem";
}else{
$str = "aaaa=". $a [$i];
}
$i + +;
}

echo "problem with data";

Reply to discussion (solution)

Break

if ($a [$i]< $b [$i]) {       echo "data is problematic";//if the condition is satisfied, exit the loop and execute the final output "data problem" directly;       Exit ();    } ...

Maybe my example doesn't express my situation.

if () {//There are many more like this, the following code is $str= "" in many if.  $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]) {       //If conditions are met, Exits the loop, directly executes the final output "data is problematic";    } else{      $str = "aaaa=". $a [$i];      

if ($condition) {
Die ("Problem with Data");
}

Correct usage is if (set) {    do something} else {   do something else}//your usage is if (set up) {   go do something} else {do something else} {  don't want to do}}

$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 ();//If the condition satisfies the call to do;       Break;//'s done, get out!    }else{      $str = "aaaa=". $a [$i];      } $i + +;}  function Buzuode () {    //do not want to do, when to do what to call}  function Xiangzuode () {///want to do
