Question

I have the following text below, what is the easiest way to parse through it?

if(typeof sa_inst.apiCB == 'function') sa_inst.apiCB({"AS":{"Query":"g","FullResults":1,"Results":[{"Type":"AS","Suggests":[{"Txt":"g<strong>oogle</strong>","Type":"AS","Sk":""},{"Txt":"g<strong>mail</strong>","Type":"AS","Sk":"AS1"},{"Txt":"g<strong>oogle</strong> <strong>maps</strong>","Type":"AS","Sk":"AS2"},{"Txt":"g<strong>oogle</strong> <strong>earth</strong>","Type":"AS","Sk":"AS3"},{"Txt":"g<strong>ames</strong>","Type":"AS","Sk":"AS4"},{"Txt":"g<strong>oogle</strong> <strong>images</strong>","Type":"AS","Sk":"AS5"},{"Txt":"g<strong>amestop</strong>","Type":"AS","Sk":"AS6"},{"Txt":"g<strong>rainger</strong>","Type":"AS","Sk":"AS7"}]}]}} /* pageview_candidate */);

I would like to only get what is after (“Txt”:) and not including the <strong> or anything else. For example, form the text above I would like to get something like:

google, gmail, google maps, google images, etc

in an array. Help please?

Answer 1

The text is JSON. Use json_decode to parse it.

$str = '{"AS":{"Query":"g","FullResults":1,"Results":[{"Type":"AS","Suggests":[{"Txt":"g<strong>oogle</strong>","Type":"AS","Sk":""},{"Txt":"g<strong>mail</strong>","Type":"AS","Sk":"AS1"},{"Txt":"g<strong>oogle</strong> <strong>maps</strong>","Type":"AS","Sk":"AS2"},{"Txt":"g<strong>oogle</strong> <strong>earth</strong>","Type":"AS","Sk":"AS3"},{"Txt":"g<strong>ames</strong>","Type":"AS","Sk":"AS4"},{"Txt":"g<strong>oogle</strong> <strong>images</strong>","Type":"AS","Sk":"AS5"},{"Txt":"g<strong>amestop</strong>","Type":"AS","Sk":"AS6"},{"Txt":"g<strong>rainger</strong>","Type":"AS","Sk":"AS7"}]}]}}';

$result = json_decode($str);

//Show all 'Txt' values
foreach($result->AS->Results[0]->Suggests as $suggests)
echo "Txt contains: ".htmlspecialchars($suggests->Txt). "<br/>";

//Show full contents of result
echo "<pre>";
print_r($result);

This outputs values of Txt first:

Txt contains: g<strong>mail</strong>  
Txt contains: g<strong>oogle</strong> <strong>maps</strong>  
Txt contains: g<strong>oogle</strong> <strong>earth</strong>  
Txt contains: g<strong>ames</strong>  
Txt contains: g<strong>oogle</strong> <strong>images</strong>  
Txt contains: g<strong>amestop</strong>  
Txt contains: g<strong>rainger</strong>  

And then the complete JSON data too:
