break out of if and foreach

Question

I have a foreach loop and an if statement. If a match is found i need to ultimately break out of the foreach.

foreach ($equipxml as $equip) {      $current_device = $equip->xpath("name");     if ($current_device[0] == $device) {          // Found a match in the file.         $nodeid = $equip->id;          <break out of if and foreach here>     } } 

Answer 1

if is not a loop structure, so you cannot "break out of it".

You can, however, break out of the foreach by simply calling break. In your example it has the desired effect:

$device = "wanted"; foreach($equipxml as $equip) {     $current_device = $equip->xpath("name");     if ( $current_device[0] == $device ) {         // found a match in the file                     $nodeid = $equip->id;          // will leave the foreach loop and also the if statement         break;         some_function(); // never reached!     }     another_function();  // not executed after match/break }

Just for completeness for others that stumble upon this question looking for an answer..

break takes an optional argument, which defines how many loop structures it should break. Example:

foreach (array('1','2','3') as $a) {     echo "$a ";     foreach (array('3','2','1') as $b) {         echo "$b ";         if ($a == $b) {              break 2;  // this will break both foreach loops         }     }     echo ". ";  // never reached! } echo "!"; 

Resulting output:

1 3 2 1 !

Answer 2

foreach($equipxml as $equip) {     $current_device = $equip->xpath("name");     if ( $current_device[0] == $device ) {         // found a match in the file                     $nodeid = $equip->id;         break;     } } 

Simply use break. That will do it.
