PHP解析错误！

我试图找出这个错误的原因（我试图使用PHP输出一些HTML）

我不知道解析错误在哪里：（。

试试这个

$newLI = "<li id = $row['id'] style='padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;'>";

$newLI=“
”；

您需要将$row['id']用大括号括起来，如

{$row['id']}

它不需要其他转义，尽管它应该用单引号括起来，用于HTML属性：

id='{$row['id']}'

因此，使用无字符串扭曲和双引号的完整答案是：

$newLI = "<li id='{$row['id']}' style='padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;'>";

$newLI=“
”；

使用单引号和字符串串联可能更容易避免这些错误：

$newLI = '<li id="'.$row['id'].'" style="padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;">';

$newLI='
；

---

此外，您不必转义HTML代码的双引号。

实际答案将是：-

$newLI = '<li id = '.$row['id'].' style="padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;">';

$newLI='
；

希望能有所帮助。

改变

$newLI = "<li id = $row['\"id\"'] style=\"padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;\">"

$newLI=“
”

致：

$rowID=$row['id']；
$newLI=“
”

---

这是因为您引用了$row['id']。

为什么不保持它的整洁和简单，如：

<?php

$newLI = "<li id =".$row['id']." style=\"padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;\">";

?>

您的问题在于$row本身

// The following is okay, as it's inside a string. Constants are not looked for
// within strings, so no E_NOTICE occurs here
print "Hello $arr[fruit]";      // Hello apple

// With one exception: braces surrounding arrays within strings allows constants
/    / to be interpreted
print "Hello {$arr[fruit]}";    // Hello carrot
print "Hello {$arr['fruit']}";  // Hello apple

// This will not work, and will result in a parse error, such as:
// Parse error: parse error, expecting T_STRING' or T_VARIABLE' or T_NUM_STRING'
// This of course applies to using superglobals in strings as well
print "Hello $arr['fruit']";
print "Hello $_GET['foo']";

// Concatenation is another option
print "Hello " . $arr['fruit']; // Hello apple

-1$row['id']无法在双引号内正确展开。这不会修复任何问题。这将导致相同的分析错误。我一直使用它，它可以正常工作correctly@MBAsfoor：不，您不需要。您可能会编写

$newLI=“
”；

如果有的话。你说得对，我很抱歉。对象属性需要大括号，但数组键不需要大括号……当我在写我的答案时出现5个答案时，我既喜欢也讨厌stackoverflow：(

$rowID = $row['id'];
$newLI = "<li id=$rowID style=\"padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;\">"

<?php

$newLI = "<li id =".$row['id']." style=\"padding-right: 20px; display:inline; border-right: 1px gray solid; margin: 0px; color: white;\">";

?>

// The following is okay, as it's inside a string. Constants are not looked for
// within strings, so no E_NOTICE occurs here
print "Hello $arr[fruit]";      // Hello apple

// With one exception: braces surrounding arrays within strings allows constants
/    / to be interpreted
print "Hello {$arr[fruit]}";    // Hello carrot
print "Hello {$arr['fruit']}";  // Hello apple
