如何刪除行並使用php文件中的已刪除指針將其他行添加到其他行？

Question

我的問題是，在這種情況下，如何根據其內容指向一行；請刪除該行，並在哪里繼續寫？

輸入文本：

[SIP34]
include => portabilidad

[SIP85]
include => portabilidad

;*

[SIP51]
include => portabilidad

這是我在文件末尾添加以下行的代碼：

$file = fopen('C:\archivos\extensions.conf', 'a+');
while(!feof($file)) {
  $line = fgets($file);
  if (stristr($line ,';*')) {
    fwrite($file,  PHP_EOL.'[new]'.PHP_EOL);
    fwrite($file, 'include => portabilidad'.PHP_EOL);
    fwrite($file,  PHP_EOL.';*'.PHP_EOL);
  }
}
fclose($file);

用我的代碼輸出文本：

[SIP34]
include => portabilidad

[SIP85]
include => portabilidad

;*

[SIP51]
include => portabilidad

[new]
include => portabilidad

;*

預期輸出：

[SIP34]
include => portabilidad

[SIP85]
include => portabilidad

[new]
include => portabilidad

;*

[SIP51]
include => portabilidad

它被消除為“; *”，並替換為“ [new]”，然后繼續寫入並放置各個標記以能夠繼續添加

輸出為“ r +”：

[SIP34]
include => portabilidad

[SIP85]
include => portabilidad

;*

[new]
include => portabilidad

;*

[SIP51]
include => portabilidad

易於閱讀，替換和編寫：

$new  = '[new]'.PHP_EOL.'include => portabilidad'.PHP_EOL.';*';
$file = 'C:\archivos\extensions.conf';
file_put_contents($file, str_replace(';*', $new, file_get_contents($file)));
