Вы можете использовать рысь с -stdin и -dump вариантов для достижения этой цели:
<?php
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the child will write to
2 => array("file", "/tmp/htmp2txt.log", "a") // stderr is a file to write to
);
$process = proc_open('lynx -stdin -dump 2>&1', $descriptorspec, $pipes, '/tmp', NULL);
if (is_resource($process)) {
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// 1 => readable handle connected to child stdout
// Any error output will be appended to htmp2txt.log
$stdin = $pipes[0];
fwrite($stdin, <<<'EOT'
