[php encode not producing =]

base64_encode is a perfect standard php encoding, but this produces = most of times. Is there an alternative making the encode by alphanumeric only?

[Replacing a phrase containing a variable]

Thanks for your suggestion, but this phrase is within a long string; the string is not limited to this phrase. I need a replacing method to look for "Note: ..... "

[Replacing a phrase containing a variable]

I have phrases in a string with the structure of "Note: some description" I want to replace "Note with (, but how can I replace the second " with )?

[get "<link" by get_meta_tags]

get_meta_tags fairly gets all meta tags within the html head starting by <meta ....

 

Is it possible to get "<link rel=..."s within the html head too ?

[file_get_contents for displaying ads]

I mean the root folder of the domain folder as /public_html/mysite.com/

[file_get_contents for displaying ads]

I put the javascript code of ad into a file named ad.html, then call it in php by

$ad = file_get_contents("http://mysite.com/ad.html");
echo $ad;

But this does not work for file_get_contents("/ad.html")

 

Is there a way to avoid writing the domain name, and just getting the ad from the file in the root folder?

[Discovering a redirecting url (like tinyurl)]

Is there a way to catch the target of a redirecting url? For example, http://tinyurl.com/KindleWireless redirects to http://www.amazon.com/Kindle-Wireless-Reading-Display-Globa lly/dp/B003FSUDM4/ref=amb_link_353259562_2?pf_rd_m=ATVPDKIK X0DER&pf_rd_s=center-10&pf_rd_r=11EYKTN682A79T370AM3&pf_rd_ t=201&pf_rd_p=1270985982&pf_rd_i=B002Y27P3M

 

How to catch the final url in php and echo it as a string?

[removing non-alphabetic characters]

There are good ways to keep only English characters in a string. But what is the easiest way to keep all alphabetic characters (whether in English or other languages like Russian, Japanese, etc) by removing all sign characters like !@#$%^&*()":;' ? 

[displaying time format]

I used the following code to convert the length in seconds to min:second format

$sec=$duration % 60;
if ($sec=="0"){
$min=$duration/60;
$duration=''.$min.':00';
}else{
$min=(($duration-$sec)/60);
$duration=''.$min.':'.$sec.'';
}

everything is OK, but it shows 35:5 instead of 35:05. I mean it disregards the first 0 when the second is 1-digit.  :-\

 

[if file_exists for calling a xml file]

Perfect solution 

[if file_exists for calling a xml file]

I want to get suggested keywords from yahoo api service. When xml file is empty (no keyword), it gives error. To resolve this problem I used this code:

if (file_exists('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2')) {
$xmlmetades = simplexml_load_file('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2');
}

 

Since it is not a normal .xml file, it is always considered no file, and return nothing.

[unique within foreach]

Thanks it works perfectly! 

[Selecting a given pattern from a string and delete everything else]

I have a string taken from an array in a foreach with the following structure

/MAINWORD/something/else ......

I want to catch only MAINWORD and remove everything else 

[unique within foreach]

I have a foreach parsing as

foreach ($posttags as $tag) {
$test = $tag->name;
$pattern = "/something/";
if(preg_match($pattern, $test)) {
$test2 = "$test is $test";
echo $test2;
}
}

 

I selected those containing a given word, but I do not know how to remove duplicates to have uniqueness. I was unable to use array_unique, as I am within a foreach loop.

[Selective adding of a string to an array]

I have a file containing lines (I mean elements separated by <br>). How I can put these lines into an array, but only those which has a given phrase.

 

Example file

I want to catch only lines which contain the word "something" and make an array.

[parsing youtube xml]

Youtube has an advanced api to deliver xml; but when I try to parse its xml, it is not well-defined. I want to get "average rating" for a given video, but simple xml load disregard this section:

$xml = simplexml_load_file('http://gdata.youtube.com/feeds/mobile/videos/wZ252E282go');
print_r($xml);

 

How can I put the value of "average rating" into an string to echo?

[parsing xml of wikipedia api]

I tried to parse wikipedia xml api by different methods, but I was unsuccessful  :'( Even the curl method did not work

    curl_setopt($ch, CURLOPT_MAXREDIRS, 4);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.1; he; rv:1.9.2. Gecko/20100722 Firefox/3.6.8");
    $page = curl_exec($ch);
    $xml = simplexml_load_string($page);
print_r($xml);

[alternative to base64_encode?]

Actually, I want to shorten a string which is incorporated into a url. It makes the url too long. I want to make the string shorter to have a shorter url. Then when going to the url, we can GET and decode the string for further processing.

[alternative to base64_encode?]

I want to encode a long string, and wish to make it shorter. base64_encode is very handy but it makes the string length longer. Is there an alternative to do the encoding/decoding with shorter encoded string length? 

[limiting the string length by the number of words]

This works well, only when the number of words are higher than the limit. If the number of words are originally lower than the limit, it returns nothing.

[limiting the string length by the number of words]

As I said, it was crude... But surely you can work with it? Or are you expecting other people to do most of the work for you?

 

No, I can replace "-"s by means of str_replace; but I am not sure if it is the simplest way to do so.

[limiting the string length by the number of words]

<?php
$subject = "word1-word2-word3-word4-word5-word6-word7";
$pattern = "/(\w*-){5}/i";
preg_match($pattern, $subject, $matches);
echo $matches[0];
?>

 

As I tried, this returns nothing.
