You can only use fopen() and file_get_contents() when fopen wrappers is enabled. This parameter is specified in the php.ini file and cannot be changed at run time using ini_set(), To know whether you can use these two function (fopen and file_get_contents) or not you can use the following code to check the value of fopen wrapper seting.
if (ini_get('allow_url_fopen') == '1') {
// use fopen() or file_get_contents()
} else {
// use CURL or fsockopen
}- if (ini_get('allow_url_fopen') == '1') {
- // use fopen() or file_get_contents()
- } else {
- // use CURL or fsockopen
- }
if (ini_get('allow_url_fopen') == '1') {
// use fopen() or file_get_contents()
} else {
// use CURL or fsockopen
}Wen you use fopen() php function to read a remote file the code is as simple as reading from a local file:
if ($fp = fopen('http://www.google.com/', 'r')) {
$content = '';
while ($line = fread($fp, 1024)) {
$content .= $line;
}
// do something with content here
// ...
} else {
// an error occured - do something here
}- if ($fp = fopen('http://www.google.com/', 'r')) {
- $content = '';
- while ($line = fread($fp, 1024)) {
- $content .= $line;
- }
- // do something with content here
- // ...
- } else {
- // an error occured - do something here
- }
if ($fp = fopen('http://www.google.com/', 'r')) {
$content = '';
while ($line = fread($fp, 1024)) {
$content .= $line;
}
// do something with content here
// ...
} else {
// an error occured - do something here
}Now, all code in one function:
function read_url_fopen($url) {
if (ini_get('allow_url_fopen') != '1') {
return '<p>ERROR - fopen wrappers is not enabled</p>';
}
if ($fp = fopen($url, 'r')) {
$content = '';
while ($line = fread($fp, 1024)) {
$content .= $line;
}
return $content;
} else {
return '<p> ERROR reading: '.$url.'</p>';
}
}- function read_url_fopen($url) {
- if (ini_get('allow_url_fopen') != '1') {
- return '<p>ERROR - fopen wrappers is not enabled</p>';
- }
- if ($fp = fopen($url, 'r')) {
- $content = '';
- while ($line = fread($fp, 1024)) {
- $content .= $line;
- }
- return $content;
- } else {
- return '<p> ERROR reading: '.$url.'</p>';
- }
- }
function read_url_fopen($url) {
if (ini_get('allow_url_fopen') != '1') {
return '<p>ERROR - fopen wrappers is not enabled</p>';
}
if ($fp = fopen($url, 'r')) {
$content = '';
while ($line = fread($fp, 1024)) {
$content .= $line;
}
return $content;
} else {
return '<p> ERROR reading: '.$url.'</p>';
}
}
