我已经用php坚持了一段时间..
在我的代码中:
for($i = 0; $i < $max;$i++){
if(//my condition){
$job_found.= $obj[$i];
}
else{
echo "jobs not found";
}
echo ($job_found);
}
如果巧合,结果将是:
阵列
但如果我尝试:
print_r ($obj[1]);
结果将是:
数组([title] =&gt; my 2title [placement] =&gt; my placement [date] =&gt; my date [time] =&gt;我的时间[网站] =&gt; http://www.g00gle.com)< / p>
如何在该位置获取数组的实际值而不仅仅是类型?

首先,正如您在自己的帖子中看到的那样,
$obj[1]
是一个数组,这意味着$obj
变量中的所有元素也很可能是数组。不幸的是,你不能只是echo
一个数组,而是遍历它以获得 echoable 数据,如下所示:
<?php
$jobsHTML = "";
for($i = 0; $i < $max;$i++){
if(!$jobsStillExist){ // CONDITION TO CHECK IF JOBS STILL EXIST
echo "jobs not found";
continue;
}
// SINCE, $obj[$i] COULD BE AN ARRAY,
// YOU NEED TO CHECK THE TYPE 1ST.
// IF IT IS A STRING, APPEND IT AS A STRING TO $jobsHTML
// OTHERWISE, LOOP THROUGH IT TO GET IT'S CONTENT...
$foundJob = $obj[$i];
if(is_array($foundJob)){
foreach($foundJob as $jobData){
$jobsHTML .= $jobData["title"] . "<br />";
$jobsHTML .= $jobData["placement"] . "<br />";
$jobsHTML .= date("d/m/Y", strtotime($jobData["date"])) . "<br />";
$jobsHTML .= $jobData["time"] . "<br />";
$jobsHTML .= $jobData["website"] . "<br /><br />";
}
}else if(is_string($foundJob)){
$jobsHTML .= $foundJob . "<br /><br />";
}
}
echo ($jobsHTML);

$job_found=array();
for($i = 0; $i < $max;$i++){
if(//my condition){
$job_found[]= $obj[$i];
}
else{
echo "jobs not found";
}
}
print_r($job_found);
你能尝试这样吗?
