Foreach loop repetition problem

This code gives four 4's and I only want one 4.. Can anyone 开发者_运维百科identify the problem??

$value1 = "0";
$entries = array($var1_1a>$var1_1b, $var1_2a>$var1_2b, $var1_3a>$var1_3b,     
$var3_1a>$var3_1b, $var3_2a>$var3_2b, $var3_3a>$var3_3b);

if (count($entries) == 0)
    echo "0";
else foreach($entries as $entry)
 { 
if($entry > $value1)
{
    echo array_sum($entries);
}
}


Why do you even have a foreach loop? echo array_sum($entries); is independent of the values you're looping through.

This should be adequate:

$entries = array($var1_1a>$var1_1b, $var1_2a>$var1_2b, $var1_3a>$var1_3b,
  $var3_1a>$var3_1b, $var3_2a>$var3_2b, $var3_3a>$var3_3b);

echo array_sum($entries);


$value1 = "0";
$entries = array($var1_1a>$var1_1b, $var1_2a>$var1_2b, $var1_3a>$var1_3b,     
$var3_1a>$var3_1b, $var3_2a>$var3_2b, $var3_3a>$var3_3b);

if (count($entries) == 0)
    echo "0";
else foreach($entries as $entry)
 { 
if($entry > $value1)
{
    echo array_sum($entries);
     break; //I think it will checking condition repeatedly 
}
}
