二进制数据读取与写入（Binary Data Read And Write）¶

二进制数据组件给应用提供二进制数据读取、写入等功能，内部使用 pack、unpack 函数实现。

二进制数据读取（Binary Data Read）¶

二进制读取相关方法请查看 Phalcon\Binary\Reader 示例：

<?php

$fp = fopen('test.bin', 'rb');

$bin = new Phalcon\Binary\Reader($fp, Phalcon\Binary::MACHINE);
$flag = $bin->readUnsignedChar();
$num = $bin->readUnsignedInt16();
$name = $bin->readString();

// 大端，高位在前
$bin = new Phalcon\Binary\Writer(NULL, Phalcon\Binary::ENDIAN_BIG);
$bin->writeUnsignedChar(1);
$bin->writeUnsignedInt16(240);
$bin->writeString('Phalcon7');
$data = $bin->getContent();

$bin = new Phalcon\Binary\Reader($data, Phalcon\Binary::ENDIAN_BIG);
echo $bin->readUnsignedChar().PHP_EOL;
echo $bin->readUnsignedInt16().PHP_EOL;
echo $bin->readString().PHP_EOL;

二进制数据写入（Binary Data Write）¶

二进制写入相关方法请查看 Phalcon\Binary\Writer 示例：

<?php

$fp = fopen('test.bin', 'wb');

$bin = new Phalcon\Binary\Writer($fp, Phalcon\Binary::MACHINE);
$bin->writeUnsignedChar(1);
$bin->writeUnsignedInt16(240);
$bin->writeString('Phalcon7');
