我无法访问数组中的值,数组看起来像这样,
Array
(
[0] => Array
(
[id] => 1661
[code] => 849651318
[job_status] => 4
[looking_for] => Lorem ipsum
[keywords_education] => Derby University
[sector_id_csv] => 10,21,9,22,26
[last_job_title_1] => Programmer
[last_job_employer_1] => HBOS
[city] => Bury
[expected_salary_level] => LEVEL_2
[education_level] => COLLEGE
[job_looking_for] =>
[is_contract] => Y
[is_permanent] => N
[is_temporary] => Y
)
)

我正在努力获取价值,我已尝试执行以下操作,
foreach ($result as $rslt) {
echo $rslt->id;
}
我也试过了,
foreach ($result as $rslt) {
$rslt['id'];
}
但这一切都不起作用,我不知道为什么,任何人都可以帮忙吗?
答案 0 :(得分:5)
在第一个例子中指出一些事情并希望澄清任何混淆:
foreach ($result as $rslt) {
echo $rslt->id;
}
箭头操作符(->
)被滥用。它通常用于在类对象上调用方法,在您的情况下$rslt
将是一个类对象,而id
将是一个方法,但事实并非如此。
在你的第二个例子中,
foreach ($result as $rslt) {
$rslt['id'];
}
你差点撞到头上的钉子,但你忘了打电话给echo
或print
将值输出到屏幕上。
此外,您的$result
数组在索引0
处有一个子数组,因此需要更改
$rslt['id'];
以及echo
或print
声明。
echo $rslt[0]['id'];
答案 1 :(得分:1)
第二个是正确的,但您错过了echo
或print
echo $rslt['id'];
从示例代码中,您不清楚$result
是什么
如果$result
包含所有列出的数组,则必须执行
foreach($result as $rslt) {
echo $rslt[0]['id'];
}

我确信有人会在接下来的0.3秒内发布答案,所以我会尝试用你的方法来帮助你。显然你知道如何使用print_r(或var_dump)。您是否尝试在阵列中的$ rslt上使用它?你似乎很难理解$ rslt是什么。
