how to fetch Javascript content using PHP?

[neoapproach]

$url_page = "http://www.somewebsite.com";
$user_agent = "Mozilla/4.0";
$string = curl_string($url_page,$user_agent);

now $string holds all the HTML/Javascript contents

how to i use PHP to extract the Javascript content?

for example Javascript:
var topic_MGID = new Array("1567564", "1568929", "1568951", "1561037", "1568755", "1534196", "1561747", "1567650", "1568941", "1568950", "1566588", "1549010", "1565487", "1567621", "1568940", "1566540", "1568899", "1568844", "1557462", "1568945", "1568745", "1567921", "1567565", "1568839", "1568057", "1568912", "1568382", "1568375", "1568760", "1568867", "1568626", "1511621", "1567480", "1567207", "1566951", "1568739", "1567096", "1560900", "1567283", "1568833");

thanks

maybe using regex?

to match anything in between:
'var topic_MGID = new Array(' and ');'

?

Welcome to WebmasterWorld neoapproach,

well, looking at that string you could split it on commas and the chop the front off. You could probably use a regex as well.

get everything between the ( and ) and then split it on comma and strip the double quotes after if you like, it really depends on what you want to do with it.

the thing is
i have entire HTML on $string

not just this line
how do i trim it down to this line?

can you give me some examples?

sorry
i'm very n00b on php

I'm not exactly sure what the scenario is, but if you are trying to get the JavaScript out of an HTML page in the variable $string, you could extract the data in the <script> tags like this:

preg_match("'<script>(.*?)<\/script>'",$string,$java);

print_r($java);

That will display the match, $java[0] will be the match with the tags included, $java[1] will be the the match inside the <script> tags.

If you have more than one occurance of <script> tags, you could use preg_match_all instead of preg_match, it will make another level in the array so look at the print_r($java).

this is my original string: "1568032", "1569051", "1557462", "1568479", "1569061", "1567564", "1569064", "1569062", "1568617", "1568929", "1569057", "1566951", "1539172", "1568836", "1540625", "1567650", "1568987", "1561747", "1569058", "1568970", "1568988", "1567565", "1568755", "1567480", "1557378", "1568239", "1569054", "1567163", "1568976", "1477551", "1569025", "1567262", "1568968", "1568057", "1532183", "1569011", "1511621", "1561037", "1569041", "1566903"

and i use split() function to split them

$array_MGID1 = split ("\".\"", $topic_MGID1);

i got this:
Array
( [0] => "1568032 => 1569051 [2] => 1557462 [3] => 1568479 [4] => 1569061 [5] => 1567564 [6] => 1569064 [7] => 1569062 [8] => 1568617 [9] => 1568929 [10] => 1569057 [11] => 1566951 [12] => 1539172 [13] => 1568836 [14] => 1540625 [15] => 1567650 [16] => 1568987 [17] => 1561747 [18] => 1569058 [19] => 1568970 [20] => 1568988 [21] => 1567565 [22] => 1568755 [23] => 1567480 [24] => 1557378 [25] => 1568239 [26] => 1569054 [27] => 1567163 [28] => 1568976 [29] => 1477551 [30] => 1569025 [31] => 1567262 [32] => 1568968 [33] => 1568057 [34] => 1532183 [35] => 1569011 [36] => 1511621 [37] => 1561037 [38] => 1569041 [39] => 1566903" )

you see on [0]... there's "1568032 and on [39]...there's 1566903"

how do i take those two quotation marks off as well?

split ("\".\"", $topic_MGID1); <-- that's how i split them

Without changing your current code much you could replace this line:

$array_MGID1 = split ("\".\"", $topic_MGID1);

with this:

$array_MGID1 = split ("\".\"", substr($topic_MGID1,1,-1));

What that does is ignores the first and last characters of the original string, in this case the quotes.

You could also use:
$array_MGID1 = explode("\",\"", substr($topic_MGID1,1,-1));

It produces the same result, it is quicker though.

thx
i got one more question

i'm writing RSS.. so it has to be in XML form

but i'm parsing a Chinese Big5 web site
it has all those funny symbols which not compatible with XML

is there any way to take out all the non-compatible characters and replace it with something else?

so it will be 100% XML form?
thanks

[neoapproach]

&#9733; <-- like those symbol
how do i use regex to replace them? so it will be okay on XML form?

[neoapproach]

&#9733; <-- like this?
how do i make it XML compatible?

[dmmh]

in a hurry are we?
