- 支持 CSV 文件的编码和解码,兼容 Excel 格式
- 支持 TSV 文件的编码和解码
- 支持 MySQL 字符串的编码和解码
- 支持字符集转换(UTF-8 和其他编码)
- 支持 BOM 头的处理
- 高性能实现,适用于大数据处理
通过 Composer 安装:
composer require foolfish3/goodcodec
- PHP >= 5.5
use GoodCodec\GoodCodec;
// 编码单个 CSV 字段
$encoded = GoodCodec::csv_encode_str("Hello, World", "UTF-8", "UTF-8", false, "\\N", ",", "\"", false);
// 编码一行 CSV 数据
$row = ["id" => 1, "name" => "John", "email" => "john@example.com"];
$encoded_row = GoodCodec::csv_encode_row($row, "UTF-8", "UTF-8", false, "\\N", ",", "\"", false);
// 编码整个 CSV 表格(Excel 兼容格式)
$data = [
["id", "name", "email"],
[1, "John", "john@example.com"],
[2, "Jane", "jane@example.com"]
];
$encoded_table = GoodCodec::csv_encode_table_excel($data, "UTF-8");
// 编码整个 CSV 表格(自定义格式)
$encoded_table = GoodCodec::csv_encode_table(
$data,
"UTF-8", // 输出字符集
"UTF-8", // 输入字符集
false, // 是否添加 BOM
"\\N", // 空值替换
",", // 分隔符
"\"", // 引号字符
false, // 是否强制引号
"\n" // 换行符
);
// 解码 CSV 字符串
$csv_string = "1,John,john@example.com\n2,Jane,jane@example.com";
$decoded = GoodCodec::csv_decode_str($csv_string, 0, "UTF-8", "UTF-8", false, ["\\N"], ",", "\"");
// 流式解码(适用于大文件)
$handle = fopen("large_file.csv", "r");
$rows = GoodCodec::csv_decode_stream(
$handle, // 文件句柄
true, // 是否关闭流
0, // 跳过行数
"UTF-8", // 输入字符集
"UTF-8", // 输出字符集
false, // 是否移除 BOM
["\\N"], // 空值标记
",", // 分隔符
"\"" // 引号字符
);
foreach ($rows as $row) {
// 处理每一行数据
}
use GoodCodec\GoodCodec;
// 编码 TSV 字段
$encoded = GoodCodec::tsv_encode_str("Hello\tWorld", "UTF-8", "UTF-8", false, "NULL");
// 编码 TSV 行
$row = ["id" => 1, "name" => "John", "email" => "john@example.com"];
$encoded = GoodCodec::tsv_encode_row($row, "UTF-8", "UTF-8", false, "\\N");
// 编码 TSV 表格
$data = [

[2, "Jane", "jane@example.com"]

// 解码 TSV 字符串
$tsv_string = "1\tJohn\tjohn@example.com";
$decoded = GoodCodec::tsv_decode_str($tsv_string, 0, "UTF-8", "UTF-8", false);
// 快速解码(性能优化版本)
$decoded_fast = GoodCodec::tsv_fast_decode_str($tsv_string, 0, "UTF-8", "UTF-8", false);
// 流式解码(适用于大文件)
$handle = fopen("large_file.tsv", "r");
$rows = GoodCodec::tsv_decode_stream($handle, true, 0, "UTF-8", "UTF-8", false);
foreach ($rows as $row) {
// 处理每一行数据
}
// 快速流式解码
$handle = fopen("large_file.tsv", "r");
$rows = GoodCodec::tsv_fast_decode_stream($handle, true, 0, "UTF-8", "UTF-8", false);
foreach ($rows as $row) {
// 处理每一行数据
}
use GoodCodec\GoodCodec;
// 编码 MySQL 字符串
$encoded = GoodCodec::mysql_encode_str("It's a string");
// 输出: 'It\'s a string'
// 解码 MySQL 字符串
$decoded = GoodCodec::mysql_decode_str("'It\'s a string'");
// 输出: It's a string
// 构建 MySQL VALUES 语句
$data = [
[1, "John", "john@example.com"],
[2, "Jane", "jane@example.com"]
];
$values = GoodCodec::mysql_build_values($data);
// 参数绑定(支持多种类型:?s 字符串,?i 整数)
$sql = GoodCodec::mysql_bind_param(
"SELECT * FROM users WHERE id = ?i AND name = ?s",
1,
"John"
);
// 批量参数绑定
$rows = [
[1, "John"],
[2, "Jane"]
];
$sql = GoodCodec::mysql_bind_param_array(
"(id = ?i AND name = ?s)",
$rows,
" OR "
);
// 输出: (id = 1 AND name = 'John') OR (id = 2 AND name = 'Jane')
$sql = GoodCodec::mysql_bind_param_array(
"(?i,?s)",
$rows,
","
);
// 输出: (1,'John'),(2,'Jane')
// 大数据分片处理
$iterator = function() {
yield [1, "John"];
yield [2, "Jane"];
};
$pieces = GoodCodec::mysql_build_values_cut_to_pieces(
"(?,?)",
$iterator(),
1000 // 每片大小
);
// SQL 词法分析
$tokens = GoodCodec::sql_token_get_all("SELECT * FROM users");
- TSV 解码提供了快速版本
tsv_fast_decode_str()
,性能约为标准版本的 8 倍 - 所有编解码方法都经过优化,适用于大数据处理
- 支持流式处理,可以处理大文件而不会占用过多内存
