How to extract and assign data from cURL output? - php

Question

The code:
function GetCurlPage ($pageSpec)
{
$ch = curl_init($pageSpec);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$tmp = curl_exec ($ch);
curl_close ($ch);
$tmp = preg_replace('/(?s)<meta http-equiv="Expires"[^>]*>/i', '', $tmp);
return $tmp;
}
$url = "https://www.domain.com/check.php?domain=" .
$domain . "&suffixes=" . $suffixes . "&fuzzysearch=" . $fuzzysearch;
$output = GetCurlPage("$url");
print $output;
It outputs 3 lines of html, however I wanted to assign a variable to each line to then do something with it...
Ie:
if ($line_1_of_output=="Hi")
{
"do something"
}
if ($line_2_of_output=="Hi")
{
"do something else"
}
How can I output each line in it's own variable in XML if this is the best way to go about it?
Thanks!

Unless I am misunderstanding you, you can just explode cURL's output and then loop through the array.
<?php
// cURL code...
$tmp = explode("<br>", $tmp);
foreach ($tmp AS $lnum => $line) {
var_dump($line);
echo '<br>';
}
Try this:
function GetCurlPage ($pageSpec)
{
$ch = curl_init($pageSpec);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$tmp = curl_exec ($ch);
curl_close ($ch);
$tmp = preg_replace('/(?s)<meta http-equiv="Expires"[^>]*>/i', '', $tmp);
$tmp = explode('<br>', $tmp);
// Test the array.
foreach ($tmp AS $line) {
echo '<pre>';
print_r($line);
echo '</pre>';
}
// Do something with each line.
$tmp[0] = str_replace('foo', 'bar', $tmp[0]);
$tmp[1] = str_replace('animal', 'monkey', $tmp[1]);
$tmp[2] = str_replace('cat', 'dog', $tmp[2]);
return $tmp;
}
