PHP语法错误

Question

I posted this question a little earlier but here is the full version. I keep getting a Syntax Error which is solved when I remove the following code. So there must be a problem here, I just can't see what it is.

The syntax error is: "The topic (none) was not found in any of the reference materials currently installed".

 <?php

$ds = 'Pear';
$sd = 'Orange';
$dt = 'Banana';
$td = 'KiwiFruit';


$FoodArray=array();

echo "<p>";

foreach ($_POST ["Gender"] as $value) {
    if ($value == Female) {
    $FoodArray=array($ds, $sd, $dt, $td);
    echo "<ul>";
foreach ($FoodArray as $key => $value)

{
    echo "<li>" . $value . "</li>";
}
    echo "</ul>";
}



?>

This is the only thing stopping me from finishing a project, so I would be grateful to anyone who can help. I will try to answer a few of your questions too.

Answer 1

The following code:

if($value == Female)

would produce a notice, not an error. However, I know from experience that someone inheriting code that relies on PHP bare strings being interpreted as strings will hate the person who wrote it for the rest of their life.

PHP Notice: Use of undefined constant Female - assumed 'female' in file on line #

Your error is you're missing a curly brace at the end. Not sure if it's just the code you posted here or if that is indeed the format of your code, but using correct indentation practices will help you avoid these types of issues, as well as help others spot check your code for you.
