Foreach循环重复问题

Question

这段代码给出了4个4，我只想要一个4 ..任何人都可以识别问题吗？

$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);
}
}

Answer 1

$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 
}
}

Answer 2

为什么你甚至有一个foreach循环？ echo array_sum($entries);与您循环的值无关。

这应该足够了：

$entries = array($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);
