创建一个数组，其中包含包含 CSV 文件中特定字符串的每一行 - Create an array with every row who contains a particular string from a CSV file

Create an array with every row who contains a particular string from a CSV file

我有这段代码，将csv文件的每一行存储到一个数组中：

$tname = myfile.csv
if ($type == 'text/csv'){
           $csvData = file_get_contents($tname);
           $lines = explode(PHP_EOL, $csvData);
           $array = array();
              foreach ($lines as $line){
                      $array[] = str_getcsv($line);
                      echo $line."<br>";
               }
}

如何仅存储包含"John is great！"字符串的整行并丢弃其他行？

你应该使用 strpos(( 或 preg_match(( 函数。

if (strpos($line, 'John is great!') !== false) {
   echo 'true';
}

或

if (preg_match('/John is great!/i',$line)) // i for case insensitive
    echo 'true';

$tname = myfile.csv
if ($type == 'text/csv'){
    $csvData = file_get_contents($tname);
    $lines = explode(PHP_EOL, $csvData);
    $array = array();
    foreach ($lines as $line){
        if (stripos($line, 'John is great!') !== false) { 
            $array[] = str_getcsv($line);
             echo $line."<br>";
        }
    }
}

我假设您想要不区分大小写的匹配
