用于php的tesseract ocr无响应

我正在使用tesseract ocr for php，我已经安装了tesseract并将路径添加到我的环境变量中，它通过命令提示符工作，但当我通过php使用它时，它返回空字符串。下面是我的php代码

<?php

require_once '../src/TesseractOCR.php';

$filepath = "text.jpeg";

$tesseractInstance = new TesseractOCR($filepath);

$result = $tesseractInstance->run();

echo $result;

$x = exec("tesseract.exe test.png test");
echo $x;

$z = (new TesseractOCR($filepath))->run();
echo $z;

$tesseract = new TesseractOCR('text.jpeg');
$y = $tesseract->run();
echo $y;

var_dump($result);
var_dump($x);
var_dump($y);
var_dump($z);

?>

谁能帮我找出问题所在以及如何解决

谢谢，

我就是这样做的：

    <?php
require_once("src/TesseractOCR.php");

$File_exe = "C:/Program Files (x86)/Tesseract-OCR/tesseract.exe";
$image = "C:/xampp/htdocs/PHP/testing.png";
$text = "C:/xampp/htdocs/PHP/out";
$output = exec("\"$File_exe\" \"$image\" \"$text\" "); //Stored the output in a text file I called "out"



$myfile = fopen("out.txt", "r","C:\xampp\htdocs\PHP") or die("No such file"); //Retrieving the output I stored in the text file(The text from the image)
echo fread($myfile,filesize("out.txt")); //Display to screen
fclose($myfile);

?>

    <?php
require_once("src/TesseractOCR.php");

$File_exe = "C:/Program Files (x86)/Tesseract-OCR/tesseract.exe";
$image = "C:/xampp/htdocs/PHP/testing.png";
$text = "C:/xampp/htdocs/PHP/out";
$output = exec("\"$File_exe\" \"$image\" \"$text\" "); //Stored the output in a text file I called "out"



$myfile = fopen("out.txt", "r","C:\xampp\htdocs\PHP") or die("No such file"); //Retrieving the output I stored in the text file(The text from the image)
echo fread($myfile,filesize("out.txt")); //Display to screen
fclose($myfile);

?>

$x=fread($myfile,filesize("out.txt");
