Description

In foreach not used third expression but in for used 3rd expression in for eaxh fetch keys and values.

in for loop firest count() and the initialization and apply condition and increment but forach is short cut

in php not set any initialization expression and not set any condition just apply and fetch keys and values 

of array 

 

 

for (initialization; condition; increment){

   code to be executed;

}

 

 

loop prints the value of array and fetch keys and values.

 

$arrayb = explode(",",$batchroomselectid);   

foreach($arrayb as $batchidkey) {

 echo $batchidkey;

 }

 

2nd exaple  

  $User = array(

    'name' => 'Boy',

    'email' => 'boy14@list.com',

    'age' => 18

);

 

foreach ($User as $key => $value) {

    echo $key.' is '.$value.'<br />';

}

$array = array( 11, 12, 23, 14, 15);        

foreach( $array as $value ) {

if( $value == 23 )continue;

echo "Value is $value <br />";
