Einführung
Wie man HTML-Code in PHP einfach analysiert, ist wahrscheinlich ein Problem, auf das jeder PHP-Benutzer stoßen wird. Mit phpQuery können Sie PHP dazu bringen, HTML-Code genauso bequem zu verarbeiten wie jQuery.

Ich habe die Onefile-Version heruntergeladen: phpQuery-0.9.5.386-onefile.zip

Dann verweisen Sie im Projekt darauf.

Ausgabe:

</span>1 => <span>string</span> 'http://www.gahe.com/thumb/12/Spiderman-City-Raid.jpg' (length=52)Der leistungsstärkste ist der pq-Selektor. Seine Syntax ähnelt der von jQuery, was sehr praktisch ist.
Das Obige stellt vor, wie man mit phpQuery HTML-Code wie JQuery analysiert, einschließlich des relevanten Inhalts. Ich hoffe, dass es für Freunde hilfreich ist, die sich für PHP-Tutorials interessieren.
