wordpress - Extract Image Sources from text in PHP - preg_match_all required -

-

i have little issue preg_match_all not running properly.

what want extract src parameter of all images in post_content wordpress string - not complete html document/dom (thus cannot use document parser function)

i using below code unfortunately untidy , works 1 image src, want image sources string

preg_match_all( '/src="([^"]*)"/', $search->post_content, $matches);  if ( isset( $matches ) ) {    foreach ($matches $match)  {  if(strpos($match[0], "src")!==false) { $res = explode("\"", $match[0]); echo $res[1]; }  }  }

can please here...

using regular expressions parse html document can error prone. in case not img elements have src attribute (in fact, doesn’t need html attribute @ all). besides that, might possible attribute value not enclosed in double quote.

better use html dom parser php’s domdocument , methods:

$doc = new domdocument(); $doc->loadhtml($search->post_content); foreach ($doc->getelementsbytagname('img') $img) {     if ($img->hasattribute('src')) {         echo $img->getattribute('src');     } }

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
