PHP CURD指的是使用PHP進行數據庫增刪改查操作。在web開發中，CURD操作是比較常見的，包括添加記錄、讀取記錄、修改記錄和刪除記錄。PHP CURD操作也非常實用，下面介紹一些常用的CURD操作代碼。 添加記錄： 在PHP CURD中，添加記錄可以通過下列代碼實現。

$con = mysqli_connect("localhost","user","password","database");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = "INSERT INTO table_name (column1, column2, column3,...)
VALUES ('value1', 'value2', 'value3',...)";
if (mysqli_query($con, $sql)) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "
" . mysqli_error($con);
}
mysqli_close($con);

讀取記錄： 讀取記錄是CURD操作中最常見的功能之一，可以通過以下代碼實現。

$con = mysqli_connect("localhost","user","password","database");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = "SELECT * FROM table_name";
$result = mysqli_query($con, $sql);
while($row = mysqli_fetch_array($result)) {
echo $row['column1'] . " " . $row['column2'];
echo "
";
}
mysqli_close($con);

修改記錄： 修改記錄的實現較為簡單，僅需要使用UPDATE語句即可。

$con = mysqli_connect("localhost","user","password","database");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = "UPDATE table_name SET column1='value1', column2='value2',... WHERE some_column=some_value";
if (mysqli_query($con, $sql)) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . mysqli_error($con);
}
mysqli_close($con);

刪除記錄： 刪除記錄也十分簡單，只需要使用DELETE語句就可以實現。

$con = mysqli_connect("localhost","user","password","database");
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql = "DELETE FROM table_name WHERE some_column=some_value";
if (mysqli_query($con, $sql)) {
echo "Record deleted successfully";
} else {
echo "Error deleting record: " . mysqli_error($con);
}
mysqli_close($con);

以上就是介紹PHP CURD操作的代碼示例。在實際開發中，需要根據具體應用選擇合適的CURD操作方式，來實現對數據庫的增刪改查操作。
