write special characters in file using php

Question

I am writting one .txt file using php. When I create it with some special charecter then it shows Ascii code for that. Like if I write a string "I don`t know" it shows "I don't know". how to write it as human redable format?

code is below

function WriteErrorLog($IntegrationId, $errorStr){
    // get integration name--------


    $integrationnameQuery = "select * from integration where IntegrationId = $IntegrationId";
    $queryRes = mysql_query($integrationnameQuery);
    $resRows = mysql_fetch_array($queryRes);
    $integrationName = $resRows['Name'];
    if(!file_exists('errors/'.$IntegrationId.'/'.date("Y.m.d").'_ErrorFile.txt')){
        $errorFile = 'errors/'.$IntegrationId.'/'.date("Y.m.d").'_ErrorFile.txt';
        $fh = fopen($errorFile, 'w') or die("can't open file");
        fwrite($fh, 'Integration Name: '.$integrationName."\r\n\r\n".date('Y-m-d H:i:s').': '.$errorStr."\r\n\r\n");
        fclose($fh);
    }else{
        $errorFile = 'errors/'.$IntegrationId.'/'.date("Y.m.d").'_ErrorFile.txt';
        $fh = fopen($errorFile, 'a+') or die("can't open file");
        fwrite($fh, date('Y-m-d H:i:s').': '.$errorStr."\r\n\r\n");
        fclose($fh);
    }
}

function CreateErrorLog($IntegrationId, $errorStr){
    if (!is_dir('./errors/'.$IntegrationId)) {
        mkdir('./errors/'.$IntegrationId);
        WriteErrorLog($IntegrationId, $errorStr);
    }else{
        WriteErrorLog($IntegrationId,  $errorStr);
    }
}

I am accessing like below

CreateErrorLog('120', 'I don`t know');

Answer 1

You can write special haracters by special codes: for example \\n is 0x0A

Or you can use function chr() for convert from ASCII code to character.

Or you can use %c in (f|s)printf functions. printf("There is zero:%c", 0x30);

如果您的代码中包含htmlspecialchars或htmlentities ，请将其删除。
