PHP - csv in_array 函数检查

Question

I am trying to pass if() statement with !in_array() check for the generated csv file.

End result is returning false for some reason, and I can not find what am I doing wrong. I am trying to pass false statement and continue with code execution.

Input:

• Array with data I want to put into csv file.

• Creating and inputing data into file.

• Getting the file

   $list = [ 0 => [ 'materials' ], 1 => [ 'products' ] ]; $testCsvFile = fopen("test.csv", "w"); foreach ($list as $fields) { fputcsv($testCsvFile, $fields); } $projectRoot = substr(strrchr(getcwd(), DIRECTORY_SEPARATOR), 1); $getFile = $projectRoot . '/test.csv'; $file = basename($getFile); if ($list && is_array($list)) { unset($parsed_data[0]); } if (!in_array($file, ['materials', 'products'])) { return false; } .... next //

you're searching the strings without reading the file you should first open the file , read it then you should find string in array, I've pasted below code just for your reference which is searching the string in csv file after opening and reading.

$file = fopen("test.csv", "r");
$str = "materials";
while (($data = fgetcsv($file)) !== false)
{
    if(in_array($str, $data))
    {
        foreach ($data as $i)
        {
            echo $i."<br>";
        }   
    }
}
fclose($file);
