Php 如果0，如何使if语句忽略var？

我想检查一个变量是否大于x，除非它是0

比如说

<?php
$max_n=10;//user setting maximum number of loops, infinite? choose 0.


//the problem is that 0 is the smallest number, so the loop stops immediately

for ($x = 0; $x <= $max_n; $x++) {
    $total_n=$x;
}

//if total number exceeds max amount of numbers, do something
if(1==1 || $total_n > $max_n )
{
    die('Total number is greater than max numbers!');
}

显然，无限循环是个坏主意，但这不是重点

如何使if语句忽略max_n if max_n=0
您可以使用该语句根据某些条件跳到下一条记录

for ($x = 0; $x <= $max_n; $x++) {
  if($max_n===0){
    continue;
  }
    $total_n=$x;
}

对于（$x=0；$x这对我来说很有帮助：

<?php
$max_n=10;//user setting maximum number of loops, infinite? choose 0.


//the problem is that 0 is the smallest number, so the loop stops immediately

for ($x = 0; $x <= $max_n; $x++) {
    $total_n=$x;
}

//if total number exceeds max amount of numbers, do something
if(1==1 || ( $total_n > 0 && $total_n > $max_n ) )
{
    die('Total number is greater than max numbers!');
}
?>

（这会使if语句始终为true），它将按预期工作。
<?php
$max_n=10;//user setting maximum number of loops, infinite? choose 0.

for ($x = 0; $x <= $max_n; $x++) {
    $total_n=$x;
}

//if total number exceeds max amount of numbers, do something
if(1==1 || ( $total_n > 0 && $total_n > $max_n ) )
{
    die('Total number is greater than max numbers!');
}
?>
