Php 数组_搜索特定值失败,即使值存在

Php 数组_搜索特定值失败,即使值存在,php,Php,我有一个非常大的PHP数组,我使用数组搜索这个数组上的预定义值。只有3个键的数组搜索失败 $headings = array("Summary ","Experience","Projects","Languages","Skills & Expertise","Education","Volunteer Experience","Certifications","Courses","Publications","Honors and Awards","Test Scores","Or

我有一个非常大的PHP数组,我使用数组搜索这个数组上的预定义值。只有3个键的数组搜索失败

 $headings = array("Summary ","Experience","Projects","Languages","Skills & Expertise","Education","Volunteer Experience","Certifications","Courses","Publications","Honors and Awards","Test Scores","Organizations","Patents");
for ($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;
      }

    } 
综上所述,体验和志愿者体验-数组搜索无法找到密钥。原因可能是什么? 这是我的阵列

按照注释中的建议,删除
$headings
数组中
“Summary”
末尾的空格

$headings = array("Summary", ...
然后,从
$cvdata
数组中删除所有前导空格或尾随空格

$cvdata = array_map('trim', $cvdata);
那么您已经拥有的代码应该可以工作了。请注意,如果在键
0
处找到项目,则在返回
array\u search
时应使用与
false
的显式比较,这将使
$key
if($key)
中计算为false。所以用

if($key === false) { ...

中的红色警告框中提到了这一点。对于您在这里的具体示例,这无关紧要,但一般来说,它肯定可以。

您是如何从文件中获取
$cvdata
的?Do
var_dump($cvdata[6])以查看。可能需要
FILE\u IGNORE\u NEW\u行
trim()
。请向我们显示
var\u dump($cvdata)的确切输出而不是
print\r()
。还请注意,在if语句中,键0将失败。
array(“Summary”
最好使用字典或数据库更好地组织数据。是的,空格是问题所在。谢谢。
if($key === false) { ...
