如果变量的值等于零，则回显文本

Question

我有这段代码：

<?php
if ( $amount < 5 ) {
  echo 'Credit Balance low! You have';
  echo $amount;
  echo ' remaining credits.';
} else {
  echo 'No recent alerts...';
}
?>

echo $amount;如果echo $00.00的值为$amount == 0我想{{1}}。我如何在我的代码中包含这个？

Answer 1

echo $amount === 0 ? '$00.00' : $amount;

Answer 2

您可能正在寻找money_format() function。

<?php echo money_format('%=0-2', $amount); ?>

=0填充0字符，-2左对齐，最小字段宽度为2.

Answer 3

if ($amount === 0) {
    echo '$0.00';
} elseif ($amount < 5) {
    echo "Credit Balance low! You have $amount remaining credits";
} else {
    echo 'No recent alerts...';
}

Answer 4

<?php
if ( $amount < 5 )
{
    echo 'Credit Balance low! You have';
    echo $amount == 0 ? '$00.00' : $amount;
    echo ' remaining credits.';
}
else
{
    echo 'No recent alerts...';
}
?>

Answer 5

你应该这样做：

<?php 

if ($amount === 0) {
  echo '$00.00';
}
elseif ($amount < 5 && $amout > 0) {
  echo 'Credit Balance low! You have' . $amount . ' remaining credits.';
}
else {
  echo 'No recent alerts...';
}
