PHP-解析错误 : syntax error, 意外 'readphp' (T_STRING)，期望 ',' 或 ';'

Question

我正在尝试使用此模板从 mysql 获取数据，但它不起作用，并且我无法在以下代码中找到错误:

<?php
$connection = mysql_connect("localhost", "root", ""); // Establishing Connection with Server
$db = mysql_select_db("company", $connection); // Selecting Database
//MySQL Query to read data
$query = mysql_query("select * from employee", $connection);
while ($row = mysql_fetch_array($query)) {
echo "<b><a href="readphp.php?id={$row['employee_id']}">{$row['employee_name']}</a></b>";
echo "<br />";
}
?>

我遇到以下错误:

Parse error: syntax error, unexpected 'readphp' (T_STRING), expecting ',' or ';'

Answer 1

你必须逃脱"当在其他引号内时 " 。更改:

echo "<b><a href="readphp.php?id={$row['employee_id']}">{$row['employee_name']}</a></b>";

致:

echo "<b><a href=\"readphp.php?id={$row['employee_id']}\">{$row['employee_name']}</a></b>";
