[SOLVED] Exploding cURL source

[Thomisback]

Hi,

 

I have made a PHP page which loads a page by using cURL. Now I want to extract a specific piece of text from the source but for some reason I can't do it.

My code:

<?php

set_time_limit(0);


$ch = curl_init("Link.example");
$usecookie = "cookie.txt"; 
       curl_setopt($ch, CURLOPT_COOKIEJAR, $usecookie);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $usecookie);    
$bestand = curl_exec($ch);

if (curl_errno($ch)){

    echo curl_error($ch);
   
}else{

    curl_close($ch);
   
}


?>

 

In the source page it says:

<option value="5d5aedc1ab7ba7e79f8ccbdd9d031131">10 Minuten</option>

Note: This value changes every time

 

I tried something like:

$data = explode("<option value=",$bestand);
foreach ($data as $value) {
echo $value;
}

 

But unfortunately this didn't work

 

Any suggestions?

try this

<?php
$strContent = <<< EOF
<option value="5d5aedc1ab7ba7e79f8ccbdd9d031131">10 Minuten</option>
EOF;


preg_match("#value=\"(.*?)\"#",$strContent,$arrMatches);

print_r($arrMatches[1]);


?>

Thanks Unfortunately I noticed the value keeps changing so I'm forced to use the explode function :/

[rajivgonsalves]

Yes it will pick up any value its regular expression change the value and see or use preg_match_all instead of preg_match

[Thomisback]

Hmm, I just tried it and the only thing it echoes is

5d5aedc1ab7ba7e79f8ccbdd9d031131

Not the "new" value

I'm trying preg_match_all now

 

Edit: Is $strContent supposed to be my cURL ouput page?

[Thomisback]

Isn't there a way to grab the text between

<option value="

and

">10 Minuten</option>

?

?

 

yep

<?php
$data = '<option value="Hello Boy">10 Minuten</option>';
if (preg_match('%<option value="(.*?)">10 Minuten</option>%', $data, $regs)) {
$result = $regs[1];
} else {
$result = "";
}
echo "found: $result"
?>

[Thomisback]

Wow thanks!

... I used it on my cURL source of a loaded page but it doesn't return anything

 

My code:

<?php

set_time_limit(0);


$ch = curl_init("X.PHP");
$usecookie = "cookie.txt"; 
       curl_setopt($ch, CURLOPT_COOKIEJAR, $usecookie);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $usecookie);    
$data = curl_exec($ch);

if (curl_errno($ch)){

    echo curl_error($ch);
   
}else{

    curl_close($ch);
   
}



if (preg_match('%<option value="(.*?)">10 Minuten</option>%', $data, $regs)) {
$result = $regs[1];
} else {
$result = "";
}
echo "found: $result"

?>

[MadTechie]

post some sample data around the ">10 Minuten</option>

 

or even try this

if (preg_match('%<option value="(.*?)">10 Minuten</option>%sim', $data, $regs)) {

 

note the sim

[Thomisback]

Thanks, when I use both your ways on

'<option value="Hello Boy">10 Minuten</option>'

It works fine, but when I try to run it onto my cURL output it doesn't return anything :S

 

 

[Thomisback]

Hmm I "fixed" it now, I first write it to a .txt file and then search it.

 

Thanks for your help

Well, if you hadn't set any other cURL options then $data wouldn't have contained the returned string, it would have just been output to the browser. You need to set RETURN_TRANSFER to true if you wish to work with the returned data rather than just outputing it straight away.

 

curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);

 

There's no reason why you should have to write it to a text file. I can only assume that in doing that you added the above option?

[Thomisback]

Ah thank you that was the line I was looking for!

Thanks a lot for that!
