php - 爆炸不能正常工作

Question

我有一个 csv 文件，我需要从中删除部分，它有 7017 行长，所以我使用 php 删除某些部分并将其重新组合在一起，相关代码如下。

$rows;
$count = 0;
while (($row = fgetcsv($files, 56000)) !== false) {
  $rows[$count] = $row;
  if (stristr($rows[$count][8], "Features:")) {
    $rows[$count][8] = str_replace("Features:", "features", $rows[$count][8]);
    $rows[$count][8] = str_replace(":", "", $rows[$count][8]);
    $rows[$count][8] = explode("features", $rows[$count][8]);
    if (isset($rows[$count][8][1])) {
      $rows[$count][8][1] = str_replace("Compatible", "compatible", $rows[$count][8][1]);
      $rows[$count][8][1] = explode("compatible", $rows[$count][8][1]);
      //$rows[$count][8][1] = explode("Compatible", $rows[$count][8][1]); produces error if  used
      $rows[$count][8][1] = explode("-", $rows[$count][8][1][0]);
    } else if (isset($rows[$count][8][0])) {
      $rows[$count][8][0] = str_replace("Compatible", "compatible", $rows[$count][8][0]);
      $rows[$count][8][0] = explode("compatible", $rows[$count][8][0]);
      //$rows[$count][8][0] = explode("Compatible", $rows[$count][8][0]); produces error if  used
      $rows[$count][8][0] = explode("-", $rows[$count][8][0][0]);
    } else {
      $rows[$count][8] = str_replace("Compatible", "compatible", $rows[$count][8]);
      $rows[$count][8] = explode("compatible", $rows[$count][8]);
      //$rows[$count][8] = explode("Compatible", $rows[$count][8]); produces error if  used
      $rows[$count][8] = explode("-", $rows[$count][8][0]);
    }
    $countif = 1;
    while (isset($rows[$count][8][1][0][$countif])) {
      $countif++;
    }
    $max = $countif - 2;
    $countif = 9;
    $counter = 1;
    while ($max <= 5 && $max >= 1 && $countif <= 13) {
      $rows[$count][$countif] = $rows[$count][8][1][0][$counter];
      $countif++;
      $counter++;
    }
    $rows[$count][8][0] = explode("Compatible", $rows[$count][8][0]);
    //$rows[$count][8] = $rows[$count][8][0][0];

  }
  $count++;
}

print_r($rows[14][8]);

问题是即使 'Compatible' 在explode 语句中引用的字符串中，它仍然是一个字符串，可以说是未分解的。输出如下。

Answer 1

这是你的问题..

这是你的第二次爆炸...

$rows[$count][8][0] = explode("Compatible", $rows[$count][8][0]); 

如果该行不包含 Features 则 $count[8] 不会分解并转换为数组。在你的 var_dump $rows[$count][8] 只是一个字符串， $rows[$count][8][0] 不存在。换行来做到这一点..

$rows[$count][8] = explode("Compatible", $rows[$count][8]);

但是您可能需要考虑将其放在 else 语句中而不是更改它。因为如果字符串包含 Features 并且已爆炸，您现在将拥有的内容将起作用。所以我建议的行应该放在 Else 语句中，以防 Features 不是字符串的一部分，并且 $rows[$count][8] 永远不会爆炸。

$rows;
$count = 0;
while (($row = fgetcsv($files, 56000)) !== false) {
  $rows[$count] = $row;
  if (stristr($rows[$count][8], "Features:")) {
    $rows[$count][8] = str_replace("Features:", "features", $rows[$count][8]);
    $rows[$count][8] = str_replace(":", "", $rows[$count][8]);
    $rows[$count][8] = explode("features", $rows[$count][8]);
    if (isset($rows[$count][8][1])) {
      $rows[$count][8][1] = str_replace("Compatible", "compatible", $rows[$count][8][1]);
      $rows[$count][8][1] = explode("compatible", $rows[$count][8][1]);
      //$rows[$count][8][1] = explode("Compatible", $rows[$count][8][1]); produces error if  used
      $rows[$count][8][1][0] = explode("-", $rows[$count][8][1][0]);
    } else if (isset($rows[$count][8][0])) {
      $rows[$count][8][0] = str_replace("Compatible", "compatible", $rows[$count][8][0]);
      $rows[$count][8][0] = explode("compatible", $rows[$count][8][0]);
      //$rows[$count][8][0] = explode("Compatible", $rows[$count][8][0]); produces error if  used
      $rows[$count][8][0][0] = explode("-", $rows[$count][8][0][0]);
    } else {
      $rows[$count][8] = str_replace("Compatible", "compatible", $rows[$count][8]);
      $rows[$count][8] = explode("compatible", $rows[$count][8]);
      //$rows[$count][8] = explode("Compatible", $rows[$count][8]); produces error if  used
      $rows[$count][8] = explode("-", $rows[$count][8][0]);
    }
    $countif = 1;
    while (isset($rows[$count][8][1][0][$countif])) {
      $countif++;
    }
    $max = $countif - 2;
    $countif = 9;
    $counter = 1;
    while ($max <= 5 && $max >= 1 && $countif <= 13) {
      $rows[$count][$countif] = $rows[$count][8][1][0][$counter];
      $countif++;
      $counter++;
    }
    $rows[$count][8][0] = explode("Compatible", $rows[$count][8][0]);
    //$rows[$count][8] = $rows[$count][8][0][0];

  }
  else // THE STRING DOESN'T CONTAIN "Features"
  {
        $rows[$count][8] = explode("Compatible", $rows[$count][8]);
  }
  $count++;
}

如果您的数据看起来像我想的那样，则不要检查字符串中是否存在“兼容”。关于什么：

if (stristr($rows[$count][8], "Features:")) {
  $rows[$count][8] = str_replace("Features:", "features", $rows[$count][8]);
  $rows[$count][8] = str_replace(":", "", $rows[$count][8]);
  $rows[$count][8] = explode("features", $rows[$count][8]);
} elseif (stristr($rows[$count][8], "Compatible:")) {
  $rows[$count][8][1] = str_replace("Compatible", "compatible", $rows[$count][8][1]);
  $rows[$count][8][1] = explode("compatible", $rows[$count][8][1]);
  $rows[$count][8][1][0] = explode("-", $rows[$count][8][1][0]);
