How to parse information in PHP? - php

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:
stdClass Object
(
[AS] => stdClass Object
(
[Query] => g
[FullResults] => 1
[Results] => Array
(
[0] => stdClass Object
(
[Type] => AS
[Suggests] => Array
(
[0] => stdClass Object
(
[Txt] => google
[Type] => AS
[Sk] =>
)
[1] => stdClass Object
(
[Txt] => gmail
[Type] => AS
[Sk] => AS1
)
[2] => stdClass Object
(
[Txt] => google maps
[Type] => AS
[Sk] => AS2
)
[3] => stdClass Object
(
[Txt] => google earth
[Type] => AS
[Sk] => AS3
)
[4] => stdClass Object
(
[Txt] => games
[Type] => AS
[Sk] => AS4
)
[5] => stdClass Object
(
[Txt] => google images
[Type] => AS
[Sk] => AS5
)
[6] => stdClass Object
(
[Txt] => gamestop
[Type] => AS
[Sk] => AS6
)
[7] => stdClass Object
(
[Txt] => grainger
[Type] => AS
[Sk] => AS7
)
)
)
)
)
)

Answer 2

This will work, but I removed ' from 'function'
<?php
echo $text = '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 */);';
echo '<br />';
$text = strip_tags($text); // remove html tags
$a = explode('"Txt":"', $text);
$app = array();
foreach ($a as $c) {
$b = explode('"', $c);
$app = $b[0];
}
unset($app[0]);
var_dump($app);
?>
