Question

值$psabad1为(i:169;i:170;i:173);这是序列化的。我想将此值转换为(169,170,173)。在此代码中，只返回第一个值(169)，而我想返回所有值(169,170,173)

$stmt1 = $db->prepare("SELECT `psabad`,`transId`,`pardakht` FROM `orders` WHERE      `transId`=?");
$stmt1->bind_param("s", $transId);
$stmt1->execute();
$stmt1->store_result();
$stmt1->bind_result($psabad1, $transid1, $pardakht1);

while ($stmt1->fetch()) {
    $pardakht =  unserialize($psabad1);
    $stmt2 = $db->prepare("SELECT `idsabad`,`idmahsool`,sabad.tedad, sabad.pardakht, pack2.titr, pack2.brand FROM `sabad` INNER JOIN pack2 ON pack2.id = sabad.idmahsool WHERE `idsabad`=?");
    $stmt2->bind_param("i", $pardakht);
    $stmt2->execute();
    $stmt2->store_result();
    $stmt2->bind_result($idsabad2, $idmahsool2,$tedad2, $pardakht2, $titr2, $brand2 );
    $stmt2->fetch();
    echo $titr2;
}

您的输出看起来很奇怪。通常，序列化数据如下所示：

a:9:{i:0;i:1;i:1;i:2;i:2;i:3;i:3;i:4;i:4;i:5;i:5;i:6;i:6;i:7;i:7;i:8;i:8;i:9;}

如果您的数据看起来与标题中的内容完全相同，如下面的$ s所示，您可以使用这个小函数检索数组：

<?php

$a = [1,2,3,4,5,6,7,8,9];
$s = 'i:1;i:2;i:3;i:4;i:5;i:6;i:7;i:8;i:9;';

var_dump($a === _unserialize($s));

function _unserialize($s){
    $i = 0;
    $_s = '';
    foreach(explode(';', trim($s, '()')) as $part){
        if($part != ''){
            $_s .= 'i:' . ($i++) . ';' . $part . ';';
        }
    }
    return unserialize('a:' . $i . ':{' . $_s . '}');
}
?>

输出：

..\php\php5.6\php.exe serialize.php
bool(true)

php反序列化值
