如何通过agi php写入文件？

#!/usr/bin/php -q

#!/usr/bin/php -q

<?php
// 获取AGI变量
$agi_variables = array();
while (!feof(STDIN)) {
    $line = trim(fgets(STDIN));
    if ($line == '') {
        break;
    }
    $parts = explode(':', $line, 2);
    $agi_variables[$parts[0]] = trim($parts[1]);
}

// 获取通话相关信息
$call_id = $agi_variables['agi_uniqueid'];
$caller_number = $agi_variables['agi_callerid'];
$callee_number = $agi_variables['agi_extension'];

// 其他处理逻辑...
?>

// 写入文件
$file_path = '/path/to/file.txt';
$file_content = 'Hello, World!';
file_put_contents($file_path, $file_content);

chmod +x write_file.php

exten => 123,1,AGI(/path/to/write_file.php)
