php structure with foreach into if

i need create a structure where after check (1)if array is not empty, i (2)check the first value in array is bigger of my_value, if is not then check second value of array and so on. when the (2) is true then run my instruction and after i need exit to loop and go to the end of the script.

If after check all value in my array (2) is never true then i need return to the 'else' of (1)

'end of script' is the same for all and contain variables changed depending of the loop

I tryed with break and goto but not working .

what is the correct structure for this.

this structure is correct?

$myvalue='value';
cart_mem_rest = array('value1','value2','value3','value4');
if( sizeof( $cart_mem_rest) != 0 ){  //condition 1           
    foreach($cart_mem_rest as $kmem => $vmem_rest){ 
        if ($vmem_rest > $myvalue){ 
            //condition 2 : if first array value is bigger of $myvalue 
            //run my instruction and go to end script, if not then check 
            //other value , and other value .....
            my instruction
            Break;//go to end script
        }
    }
}else{ 

    //here if conditions 1 or 2 are not verificated
    if(condition is true ){
         
        my instruction
    }else{
        my instruction         
    }
}
//end script
echo ' end script';
