我有一个非常大的PHP数组，我使用array_search来获取此数组的预定义值。仅对于3个键，array_search失败
$headings = array("Summary ","Experience","Projects","Languages","Skills & Expertise","Education","Volunteer Experience","Certifications","Courses","Publications","Honors and Awards","Test Scores","Organizations","Patents");
for ($x = 0; $x <= 13; $x++) {
$present = $headings[$x];
$key = array_search($present, $cvdata, true);
if($key) {
echo "<br />"; echo "Key Present-----------------".$present.$key;
}else {
echo "<br />"; echo "No Match-----------".$present;
}
}
上述代码的输出为
No Match-----------Summary
No Match-----------Experience
Key Present-----------------Projects20
Key Present-----------------Languages41
Key Present-----------------Skills & Expertise46
Key Present-----------------Education58
No Match-----------Volunteer Experience
Key Present-----------------Certifications71
Key Present-----------------Courses79
Key Present-----------------Publications251
Key Present-----------------Honors and Awards259
Key Present-----------------Test Scores267
Key Present-----------------Organizations277
Key Present-----------------Patents285
总结，经验和志愿者经验 - array_search无法找到密钥。可能是什么原因？ 这是我的阵列。

答案 0 :(得分：0)
按照评论中的建议，从"Summary "数组中的$headings末尾删除空格。
$headings = array("Summary", ...
然后，从$cvdata数组中删除任何前导或尾随空格。
$cvdata = array_map('trim', $cvdata);
然后你已经拥有的代码应该工作。请注意，如果在密钥false上找到某个项目，则应在array_search返回时使用与0的显式比较，这会使$key在if ($key)评估为false {1}}。所以改为使用
if($key === false) { ...
the documentation for array_search中的红色警告框中提到了这一点。对于你这里的具体例子来说无关紧要，但总的来说肯定可以。
