php入門–file_get_contents()とcurl関数でコンテンツを取得する

1.file_get_contents
<?php
$url = “http://www.xxx.com”;
$contents = file_get_contents($url);

//$getcontent = iconv(“shift-jis”, “utf-8”,$contents);
echo $contents;
?>
2.fopen->fread->fclose
<?php
$handle = fopen (“http://www.xxx.com”, “rb”);
$contents = “”;
do {
$data = fread($handle, 1024);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose ($handle);
echo $contents;
?>
3.curl
<?php
$url = “http://www.xxx.com”;
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
//curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
//curl_setopt($ch, CURLOPT_USERPWD, US_NAME.”:”.US_PWD);
$contents = curl_exec($ch);
curl_close($ch);
echo $contents;
