查找字符串的一部分并将其从数组中删除 [英] Find part of a string and remove it from an array

问题描述

我需要找到哪个键包含值的一部分并且不显示它

i need to find which is the key containing the part of the value and doesn't show it

$arr = array(0 => "helbor_000", 1 => "ez_000", 2 => "xx_333");
    $find = "helb";
    $key = array_search($find, $arr);
    foreach($arr as $index => $value){
          if($index != $key){
              echo $value;
          }
    }

推荐答案

preg_grep（）可以做到

$arr = array(0 => "helbor_000", 1 => "ez_000", 2 => "xx_333");
$find = "~^helb.*$~";
$ret = preg_grep($find, $arr, PREG_GREP_INVERT);
print_r($ret);
