PHP;分配fgets（）输出到一个数组 [英] PHP; assigning fgets() output to an array

问题描述

我试图将PHP $中的 fgets（）函数返回给一个数组。我已经尝试过测试字符串，他们工作正常。我还确认 fgets（）正在返回项目，但仍然没有快乐。考虑到这可能是一个计时问题，我有函数运行 onload ，这是行不通的。我的代码在下面;

$ p $函数createDataArray（）

global $ resultsArray;

$ i = 0;
$ file = fopen（downloads / E0.csv，r）; $！
$ b while（！feof（$ file））
{
$ line = fgets（$ file，4096）;
$ resultsArray [$ i] = $ line; //这不行。亦范范辛读方亦预这是一个字符串，但它不会被分配给数组。
$ i = $ i + 1;
}
fclose（$ file）;

解决方案

函数createDataArray（）
{
$ resultsArray = array（）;

$ file = fopen（downloads / E0.csv，r）; $！
$ b while（！feof（$ file））
{
$ line = fgets（$ file，4096）;
$ resultsArray [] = $ line;
}
fclose（$ file）;

return $ resultsArray;
}

I am attempting to assign the string returned by the fgets() function to an array in PHP. I have tried test strings and they work fine. I have also made sure that fgets() is returning items, but still no joy. Thinking that it may be a timing issue, I had the function run onload and that didn't work. My code is below; any help on this would be much appreciated.

function createDataArray()
    {
        global $resultsArray;

        $i = 0;
        $file = fopen("downloads/E0.csv","r");

        while(! feof($file))
        {
            $line = fgets($file, 4096);
            $resultsArray[$i] = $line; //This isn't working. Something is wrong with $line. It is a string, but it doesn't get assigned to the array.
            $i = $i + 1;
        }
        fclose($file);
    }

解决方案

PLEASE return the array; do not use globals.

This fix should work:

function createDataArray()
    {
        $resultsArray = array();

        $file = fopen("downloads/E0.csv","r");

        while(! feof($file))
        {
            $line = fgets($file, 4096);
            $resultsArray[] = $line; 
        }
        fclose($file);

        return $resultsArray;
    }
