Welcome to my world
preg_match_all match the regexp in all the $html string and output everything as
an array in $result. “i” option is used to make it case insensitive
preg_match_all('/<img[^>]+>/i',$html, $result);
print_r($result);
Get the metadata
$img = array();
foreach( $result as $img_tag)
{
preg_match_all('/(alt|title|src)=("[^"]*")/i',$img_tag, $img[$img_tag]);
}
print_r($img);
Here you go.
With PHPs’ simple xml functions it is possible to read xml easily. However, that doesn’t work any longer when a tag contains a colon. That tag is simply ignored and can’t be accessed. Often in RSS feeds there is content:encoded.
There is a trick. Instead of using simplexml_load_file use
$feed = file_get_contents($url);
$feed = str_replace("<content:encoded>", "<contentEncoded>", $feed);
$feed = str_replace("</content:encoded>", "</contentEncoded>", $feed);
$xml = simplexml_load_string($feed);
have fun!
Imagine you have a var variable containing: <div>I'm happy</div>.
On index.twig, {{ var }} will render <div>I'm happy</div>.
On index.html.twig, {{ var }} will render <div>I'm happy<div>
On index.js.twig, {{ var }} will render \x3Cdiv\x3EI\x27m\x20happy\x3Cdiv\x3E
And so on.
Always use the right extension to avoid any XSS vulnerability, and
always use |raw wisely because it overlaps this extension’s implicit protection.
When ever I tried to insert text from the clipboard to vim it did either not work at all or the lines were inserted like a tree, each line more indented.
Installing or updating a global installed composer can be a PITA if you don’t want to rely on the Linux distro
An easy way is:
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/bin --filename=composer

__toString() must not throw an exception.
If you an exception handler even that seems fail (in itself) with __toString() must not throw an exception. There is no nice safe way to handle it. The easiest solution is to catch that error as well. It might seems to be odd, but on the other hand the exception hanler shall not fail ;)
