爆炸不正常

标签： php string explode

我有一个csv文件，我需要删除它的部分，并且它的长度为7017行，所以我使用php删除某些部分并将其重新组合在一起，相关的代码如下所示。 

$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]);

问题在于，即使'exploble'在爆炸声明中引用的字符串中，它仍然是一个单独的字符串，可以说是未爆炸的。输出如下。

这是你的问题..

它是你的第二次爆炸...... 

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

如果该行不包含Features，则$ count [8]不会展开并调入数组。在你的var_dump $ rows中[$ count] [8]只是一个字符串而$ rows [$ count] [8] [0]不存在。更改行来执行此操作.. 

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

但你可能不想考虑将其放在else语句中而不是改变它。因为如果字符串包含Features并且爆炸，你现在拥有的东西将会起作用。因此，我建议的行应该在Else语句中，因为功能不是字符串的分开而且$ 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++;
}

答案 1 :(得分：0)

如果您的数据与我的想法相符，则不会检查字符串中是否存在“兼容”。怎么样：

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]);
