i have already succesfully translated some quotes via my translation function __(); and now I want to echo only one of those quotes at random. All quotes are separated in this string with a special character like a |
Sofar I only have this. What code could should go below this tackle my random echo?
$quotes =
__("IF YOU MAKE EVERYTHING BOLD, NOTHING IS BOLD") . "|" .
__("Quality of design is an indicator of credibility") . "|" .
__("People ignore design, that ignores people");
(An important restriction: it is essential that the quotes be exactly closed with __(" and "); sothat they can be checked and translated.) __($variable) doest not work with current clean up scripts that I have bought so these won't work.
You're already calling __() on each of your quotes individually, why not save all the extra translating and do something like:
$quotes = array('quote1', 'quote2', 'quote3');
$index = array_rand($quotes);
echo __($quotes[$index]);
Edit: To satisfy your other requirement, that the call to __() must immediately surround each string, you could do this:
$quotes = array(__('quote1'), __('quote2'), __('quote3'));
$index = array_rand($quotes);
echo $quotes[$index];
The big downside here is that you're now looking up a translation for every string in that array, even though only one is printed, but that's the same situation you had in the "one big string" solution.
Why don't you keep them in an array and translate only what is actually outputted?
$quotes = array(
"IF YOU MAKE EVERYTHING BOLD, NOTHING IS BOLD",
"Quality of design is an indicator of credibility",
"People ignore design, that ignores people",
);
$randomQuote = $quotes[ rand(0, count($quotes)-1)];
echo __($randomQuote);
Why the biscuits are they all in one string, and not an array? Your problem would be immediately solved if this was the case. As stands, split in | and index randomly into the array created to pick a random quote.

OK, so I shave my head, but if I had hair I wouldn't need a razor because I'd have torn it all out tonight. It's gone 3am and what looked like a simple solution at 00:30 has become far from it.
Please see the code extract below..
$psusername = substr($list[$count],16);
if ($psusername == $psu_value){
$answer = "YES";
}
else {
$answer = "NO";
}
$psusername holds the value "normann" which is taken from a URL in a text based file (url.db)
$psu_value also holds the value "normann" which is retrieved from a cookie set on the user's computer (or a parameter in the browser address bar - URL).
However, and I'm sure you can guess my problem, the variable $answer contains "NO" from the test above.
All the PHP I know I've picked up from Google searches and you guys here, so I'm no expert, which is perhaps evident.
Maybe this is a schoolboy error, but I cannot figure out what I'm doing wrong. My assumption is that the data types differ. Ultimately, I want to compare the two variables and have a TRUE result when they contain the same information (i.e normann = normann).
So if you very clever fellows can point out why two variables echo what appears to be the same information but are in fact different, it'd be a very useful lesson for me and make my users very happy.
Do they echo the same thing when you do:
echo gettype($psusername) . '\n' . gettype($psu_value);
Since i can't see what data is stored in the array $list (and the index $count), I cannot suggest a full solution to yuor problem.
But i can suggest you to insert this code right before the if statement:
var_dump($psusername);
var_dump($psu_value);
and see why the two variables are not identical.
The var_dump function will output the content stored in the variable and the type (string, integer, array ec..), so you will figure out why the if statement is returning false
Since it looks like you have non-printable characters in your string, you can strip them out before the comparison. This will remove whatever is not printable in your character set:
$psusername = preg_replace("/[[:^print:]]/", "", $psusername);
0D 0A is a new line. The first is the carriage return (CR) character and the second is the new line (NL) character. They are also known as \r and \n.
You can just trim it off using trim().
$psusername = trim($psusername);
Or if it only occurs at the end of the string then rtrim() would do the job:
$psusername = rtrim($psusername);
If you are getting the values from the file using file() then you can pass FILE_IGNORE_NEW_LINES as the second argument, and that will remove the new line:
$contents = file('url.db', FILE_IGNORE_NEW_LINES);
I just want to thank all who responded. I realised after viewing my logfile the outputs in HEX format that it was the carriage return values causing the variables to mismatch and a I mentioned was able to resolve (trim) with the following code..
$psusername = preg_replace("/[^[:alnum:]]/u", '', $psusername);
I also know that the system within which the profiles and usernames are created allow both upper and lower case values to match, so I took the precaution of building that functionality into my code as an added measure of completeness.
And I'm happy to say, the code functions perfectly now.
Once again, thanks for your responses and suggestions.
I've got a script which generates text. I need to be strip all repeated blocks of text. The string is in xml format, so I can use the beginning and ending tags to determine where the strings are. I've been using substr_replace to remove the unnecessary text... However, this only works if I know how many times said text is going to be present in the string. Example :
<container>
<string1>This is the first string.</string>
<string2>This is the second string.</string>
<stuff>This is the important stuff.</stuff>
</container>
That container might appear once, twice six times, seven times, whatever. The point is, it's necessary to only have it appear once in the string variable. Right now this is what I'm doing.
$where_begin = strpos($wsman_output,'<container');
$where_end = strpos($wsman_output,"</container>");
$end_length = strlen("</Envelope>");
$attack = $where_end - $where_begin;
$attack = $attack + $end_length;
$wsman_output = substr_replace($wsman_output,"",$where_begin,$attack);
And I do that for each time the container exists.... However, I just found out that it's not always going to be the same.. Which really messes things up.
Any ideas?
In the end I decided to use the method suggested here.
I pulled each block of string I wanted from the variable, then combined them back together in the required order.
I'm currently trying out this PHP preg_replace function and I've run into a small problem. I want to replace all the tags with a div with an ID, unique for every div, so I thought I would add it into a for loop. But in some strange way, it only do the first line and gives it an ID of 49, which is the last ID they can get. Here's my code:
$res = mysqli_query($mysqli, "SELECT * FROM song WHERE id = 1");
$row = mysqli_fetch_assoc($res);
mysqli_set_charset("utf8");
$lyric = $row['lyric'];
$lyricHTML = nl2br($lyric);
$lines_arr = preg_split('[<br />]',$lyricHTML);
$lines = count($lines_arr);
for($i = 0; $i < $lines; $i++) {
$string = preg_replace(']<br />]', '</h4><h4 id="no'.$i.'">', $lyricHTML, 1);
echo $i;
}
echo '<h4>';
echo $string;
echo '</h4>';
How it works is that I have a large amount of text in my database, and when I add it into the lyric variable, it's just plain text. But when I nl2br it, it gets after every line, which I use here. I get the number of by using the little "lines_arr" method as you can see, and then basically iterate in a for loop.
The only problem is that it only outputs on the first line and gives that an ID of 49. When I move it outside the for loop and removes the limit, it works and all lines gets an <h4> around them, but then I don't get the unique ID I need.
This is some text I pulled out from the database
Mama called about the paper turns out they wrote about me
Now my broken heart´s the only thing that's broke about me
So many people should have seen what we got going on
I only wanna put my heart and my life in songs
Writing about the pain I felt with my daddy gone
About the emptiness I felt when I sat alone
About the happiness I feel when I sing it loud
He should have heard the noise we made with the happy crowd
Did my Gran Daddy know he taught me what a poem was
How you can use a sentence or just a simple pause
What will I say when my kids ask me who my daddy was
I thought about it for a while and I'm at a loss
Knowing that I´m gonna live my whole life without him
I found out a lot of things I never knew about him
All I know is that I´ll never really be alone
Cause we gotta lot of love and a happy home
And my goal is to give every line an <h4 id="no1">TEXT</h4> for example, and the number after no, like no1 or no4 should be incremented every iteration, that's why I chose a for-loop.
Looks like you need to escape your regexp
preg_replace('/\[<br \/\]/', ...);
Really though, this is a classic XY Problem. Instead of asking us how to fix your solution, you should ask us how to solve your problem.
Show us some example text in the database and then show us how you would like it to be formatted. It's very likely there's a better way.
I would use array_walk for this. ideone demo here
$lines = preg_split("/[\r\n]+/", $row['lyric']);
array_walk($lines, function(&$line, $idx) {
$line = sprintf("<h4 id='no%d'>%s</h4>", $idx+1, $line);
});
echo implode("\n", $lines);
Output
<h4 id="no1">Mama called about the paper turns out they wrote about me</h4>
<h4 id="no2">Now my broken heart's the only thing that's broke about me</h4>
<h4 id="no3">So many people should have seen what we got going on</h4>
...
<h4 id="no16">Cause we gotta lot of love and a happy home</h4>
Explanation of solution
nl2br doesn't really help us here. It converts \n to <br /> but then we'd just end up splitting the string on the br. We might as well split using \n to start with. I'm going to use /[\r\n]+/ because it splits one or more \r, \n, and \r\n.
$lines = preg_split("/[\r\n]+/", $row['lyric']);
Now we have an array of strings, each containing one line of lyrics. But we want to wrap each string in an <h4 id="noX">...</h4> where X is the number of the line.
Ordinarily we would use array_map for this, but the array_map callback does not receive an index argument. Instead we will use array_walk which does receive the index.
One more note about this line, is the use of &$line as the callback parameter. This allows us to alter the contents of the $line and have it "saved" in our original $lyrics array. (See the Example #1 in the PHP docs to compare the difference).
array_walk($lines, function(&$line, $idx) {
Here's where the h4 comes in. I use sprintf for formatting HTML strings because I think they are more readable. And it allows you to control how the arguments are output without adding a bunch of view logic in the "template".
Here's the world's tiniest template: '<h4 id="no%d">%s</h4>'. It has two inputs, %d and %s. The first will be output as a number (our line number), and the second will be output as a string (our lyrics).
$line = sprintf('<h4 id="no%d">%s</h4>', $idx+1, $line);
Close the array_walk callback function
});
Now $lines is an array of our newly-formatted lyrics. Let's output the lyrics by separating each line with a \n.
echo implode("\n", $lines);
Done!
If your text in db is in every line why just not explode it with \n character?
Always try to find a solution without using preg set of functions, because they are heavy memory consumers:
I would go lke this:
$lyric = $row['lyric'];
$lyrics =explode("\n",$lyrics);
$lyricsHtml=null;
$i=0;
foreach($lyrics as $val){
$i++;
$lyricsHtml[] = '<h4 id="no'.$i.'">'.$val.'</h4>';
}
$lyricsHtml = implode("\n",$lyricsHtml);
An other way with preg_replace_callback:
$id = 0;
$lyric = preg_replace_callback('~(^)|$~m',
function ($m) use (&$id) {
return (isset($m[1])) ? '<h4 id="no' . ++$id . '">' : '</h4>'; },
$lyric);
I need some assistance with php. I have been trying several things for the past several days including str_replace to no avail.
I have a field that may contain from 1 to 20 values, all listed on their own line, there is no html code in that field to separate them and some of the values may have their own spaces in between, so separating by space doesnt work.
What I need is to extract every single string of each line and convert it to code.
<p>For example, my field with values looks like this: </p>
<p><b>lang_fld </b><br>
------
<br>
English<br>
Spanish<br>
German<br>
French</p>
What I have in mind is to extract each line, ex. "English" from that string, and create a line of code like
<img src="images/flags/english.png> English
Basically I want to add the flag graphic to the word
I already tried
echo str_replace('English','<img src="images/flags/english.png>,lang_fld)<br>
...and so on
what I get after going through every single possible value is a bunch error
messages (different every time since I keep making changes - by guessing)
Can someone offer an easier option to do this? Not all 20 values will be in
that areatext field, some may contain just one language, some ten, some all 20,
etc.
Thank you!
Assuming you have all the values on a separate line, you can do explode() on the string to convert it to array of separate items, then loop through the array with foreach and perform any modifications with the single item. After you are done with the items and you would like to get them back together, you can use implode() to combine them into a single string.
A short sample ( you can of course use a for loop, I just prefer foreach here as it shows you better what is happening with the data ):
$text =
"French language
Italian language
English language";
$items = explode( "\n", $text ); // Split by newline ( you can also use "<br>" as separator )
$result = array(); // Modified data will be placed here
foreach ( $items as $item )
{
// Do something with $item
$item = "<img src=\"images/flags/$item.png\"> $item";
$result[] = $item;
}
// Merge them back together
$text = implode("\n", $result);
I need to generate a link with a Javascript confirmation dialog using Symfony's link_to() method. The confirmation dialog text gets some of it's content from a database entry:
<?php echo link_to( "click here", 'category/delete?id='.$id, array( 'confirm' => 'Are you sure you want to delete the category: '.$category->getName().'?' ) ) ?>
But if the database entry has a single quote in it, the confirm dialog doesn't work because the generated JS is surrounded with single quotes. So if I have a category called "John's Articles", the generated JS starts like this:
<a onclick="if (confirm('Are you sure you want to delete the category: John's Articles?')) { var f = document.createElement('form'); f.styl.... etc... "
So, the single quote in there screws up the confirmation, etc...
Anyways I thought I would simply run $category->getName() through addslashes() but it didn't add any slashes... I also tried saving out the category name as a separate variable ahead of time and adding slashes to that. But it didn't add any. Then I started looking at Symfony's escaping methods and found methods like esc_entities() but they resulted in the text looking like John's Articles.
What do I do? All I want to do is add in a single slash before single quotes in that string. I never tried str_replace("'","\'",$category->getName()) but THAT didn't even do anything. I can create my own basic string in my template like Alex's Test and addslashes() to it just fine. It's just this value from the database that I can't add any slashes to.
When I look at the value in the database, it looks just like John's Articles. There are no special characters or encoded characters.
What am I missing here?
UPDATE
I've tried the following code with the following results:
echo $category->getName()."<br/>";
echo addslashes($category->getName())."<br/>";
$tmp = $category->getName();
echo addslashes($tmp)."<br/>";
$tmp = addslashes($category->getName());
echo $tmp."<br/>";
$tmp = "Testing's the Testing";
echo addslashes($tmp)."<br/>";
$tmp = str_replace("'","\\'",$category->getName());
echo $tmp;
Results:
John's Articles
John's Articles
John's Articles
John's Articles
Testing\'s the Testing
John's Articles
The values from the database simply will not get slashes added to them...
Seems like you just use
addslashes($category->getName())
But you need assign returned value to other variable, ex.
$nameWithSlashes=addslashes($category->getName())
use json_encode() when inserting into Javascript. It's specifically intended to turn arbitrary data structures into syntactically valid Javascript.
<?php echo link_to( ....snip snip... category: '. json_encode($category->getName()) .'?' ) ) ?>
^^^^^^^^^^^^ ^
will take care of the problem, without any "risky" regexes/string replacements.
