Php continue and break process control language usage

Continue
Continue is used in the loop structure to skip the remaining code in this loop and start executing the next loop.

Note: in the php Tutorial, the switch statement is considered as a loop structure for the purpose of continue.

Continue accepts an optional numeric parameter to decide to skip multiple cycles to the end of the loop.

 

<? Php
While (list ($ key, $ value) = each ($ arr )){
If ($ key = "zhoz") {// if the queried object value is zhoz, this record will not be displayed.
Continue;
}
Do_something ($ value );
}
// Example 2
Foreach ($ list as $ temp ){
If ($ temp-> value = "zhoz "){
Continue; // if the queried object value is zhoz, this record will not be displayed.
}
Do_list; // records in the array are displayed here.
}
?>

Break
Break ends the execution of the current for, foreach, while, do... while or switch structure.

The break can accept an optional numeric parameter to determine the number of loops to jump out.

<? Php
$ Arr = array ('one', 'two', 'Three ', 'Four', 'stop', 'five ');
While (list (, $ val) = each ($ arr )){
If ($ val = 'stop '){
Break;/* you coshould also write 'break 1; 'here .*/
   }
Echo "$ val <br> n ";
}

/* Using the optional argument .*/

$ I = 0;
While (++ $ I ){
Switch ($ I ){
Case 5:
Echo "at 5 <br> n ";
Break 1;/* exit only the switch .*/
Case 10:
Echo "at 10; quitting <br> n ";
Break 2;/* exit the switch and the while .*/
Default:
Break;
   }
}
?>

Instance 2

 

<? Php
$ I = 0;
While ($ I <7 ){
If ($ arr [$ I] = "stop "){
Break;
}
$ I ++;
}
?>
