## Loading documents
|
||
|
|
* phpQuery::**newDocument**($html, $contentType = null) Creates new document from markup. If no $contentType, autodetection is made (based on markup). If it fails, text/html in utf-8 is used.
|
||
|
|
* phpQuery::**newDocumentFile**($file, $contentType = null) Creates new document from file. Works like newDocument()
|
||
|
|
* phpQuery::**newDocumentHTML**($html, $charset = 'utf-8')
|
||
|
|
* phpQuery::**newDocumentXHTML**($html, $charset = 'utf-8')
|
||
|
|
* phpQuery::**newDocumentXML**($html, $charset = 'utf-8')
|

## pq function
|
||
|
|
**`pq($param, $context = null);`**
|
||
|
|
|
||
|
|
**pq();** function is equivalent of jQuery's **$();**. It's used for 3 type of things:
|
||
|
|
1. Importing markup
|
||
|
|
```
|
||
|
|
// Import into selected document:
|
||
|
|
// doesn't accept text nodes at beginning of input string
|
||
|
|
pq('<div/>')
|
||
|
|
// Import into document with ID from $pq->getDocumentID():
|
||
|
|
pq('<div/>', $pq->getDocumentID())
|
||
|
|
// Import into same document as DOMNode belongs to:
|
||
|
|
pq('<div/>', DOMNode)
|
||
|
|
// Import into document from phpQuery object:
|
||
|
|
pq('<div/>', $pq)
|
||
|
|
```
|
||
|
|
1. Running queries
|
||
|
|
```
|
||
|
|
// Run query on last selected document:
|
||
|
|
pq('div.myClass')
|
||
|
|
// Run query on document with ID from $pq->getDocumentID():
|
||
|
|
pq('div.myClass', $pq->getDocumentID())
|
||
|
|
// Run query on same document as DOMNode belongs to and use node(s)as root for query:
|
||
|
|
pq('div.myClass', DOMNode)
|
||
|
|
// Run query on document from phpQuery object
|
||
|
|
// and use object's stack as root node(s) for query:
|
||
|
|
pq('div.myClass', $pq)
|
||
|
|
```
|
||
|
|
1. Wrapping DOMNodes with phpQuery objects
|
||
|
|
```
|
||
|
|
foreach(pq('li') as $li)
|
||
|
|
// $li is pure DOMNode, change it to phpQuery object
|
||
|
|
pq($li);
|
||
|
|
```
