PHP - Get Substring After Specific Char Position Up To Occurence Of Another Char

Hi all

I am trying to loop through an array and output as JSON.
What I'm looking to do is create something like:

Code: [Select]
  "something": [
{"title":"Test 1"},
{"title":"Test 2"}
],

Notice that the final row has no comma.

My code is as follows:


<?php foreach($something as $thing): ?>
<?php $something_array = array('title'=>$thingt->getId()); ?>
<?php echo json_encode($something_array).','."\n"; ?>
<?php endforeach; ?>


I had to add a comma to the end of the array, or the JSON rows would not be ended with one.

How can I get it so that, no matter how many items are in the array, the last row, wil not have the comma at the end?

With the comma at the end, my JSON doesn't validate

Thanks

I have a list of pictures and I want to control the order.


Here is the picture format:
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_1.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_2.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_3.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_4.jpg
$pic = http://www.picture.biz/incoming/w_2GTEK13T961240561_5.jpg

Notice the order 1.jpg, 2.jpg, etc..

Here is where I'm stuck...

// begin stuck :)
$orderPic = explode("_", $pic);

foreach($orderPic as $rank){
     echo "$rank"; // I need $rank to equal 1 then 2 then 3 ...
}


It would be nice actually if I could start the insert with number 2 because number one is always a screwy picture.

I hope this makes sense /  Thank for the help!

I have the following code:

Code: [Select]
$str = ($stringcontents[$step+38]);
$str1 = ord($str);
$bgcolor = convertchar($str1);
?>
<td bgcolor='<?php echo $bgcolor;?>'>
<span title='<?php echo $fieldname;?>' style='color: <?php echo $fgcolor;?>; font-size: 12pt'><font color="<?php echo $fgcolor;?>"><?php echo $stringcontents[$step];?></font></span>

the convertchar function takes the ord value of the ASCII chr and sets a variable for bgcolor and fgcolor using HTML color codes.  The background sets correctly, but the foreground ASCII chr is always black and does not use the font color code.

What do I need to do to get the ASCII chr to change to a color other than black?


Added:
I am using a default charset:

<META http-equiv="Content-Type" content="text/html; charset=IBM437">

Code:

Code: [Select]
PostInfo,color-main,Newman,not-collapsed;Friends,color-main2,Top Friends,not-collapsed||Twitter,color-main2,Twitter,not-collapsed;Signature,color-main2,Signature,not-collapsed;AboutMe,color-transparent,About Me,not-collapsed

Now I want make a function like

if PostInfo = "not-collapsed" = do this/etc,


So simply, how do I extract some content out of this and then use each thing to equal to if it's 'not-collapsed' or 'collapsed' ?

Very hard but i think possible? ty

Hi guys, thank for any help. This does not appear like a difficult problem but it has me stymied. I have several selects, the 1st item of each is "--Specify--" so that the user has to specifically choose an item. Once an item is selected on any select the others should be set to the 1st item or "--Specify--" to avoid confusion.

If you want to see the complete code it on this web page: http://chordsandguitar.com/progressions-test.php

The relevant code is:

Code: [Select]
if ($prog1_menu != "--Specify1--")
{
$prog2_menu = "--Specify--";
echo "set prog2 to Specify";
}

if ($prog2_menu != "--Specify2--")
{
$prog1_menu = "--Specify--";
echo "set prog1 to Specify";
}

echo "<form action = \"progressions-test.php?s_sort_all=$sort_all&s_prog1_menu=$prog1_menu&s_prog2_menu=$prog2_menu&s_prog1_trigged=$prog1_trigged&s_prog2_trigged=$prog2_trigged\" method = \"GET\">";
//also stores the values of the drop-downs when Select button is pushed so they can be retrieved when the web page is loaded again



echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Ascending bass line";
echo "<br />";
echo "Select a progression: <a href=\"http://www.chordsandguitar.com/progressions-test.php?s_sort_all=All&s_prog1_menu=--Select--&s_prog2_menu=--Select--\"\"><big>ALL</big></a>";
echo "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";

echo "<select name=\"prog1_menu\"  onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify1--\">--Specify--</option>";
if ($prog1_menu == "ii-iii-IV-V progression") echo "<option SELECTED value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
else echo "<option value=\"ii-iii-IV-V progression\">ii-iii-IV-V progression</option>";
if ($prog1_menu == "I-ii-IV-V progression") echo "<option SELECTED value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
else echo "<option value=\"I-ii-IV-V progression\">I-ii-IV-V progression</option>";
if ($prog1_menu == "I-iii-IV-V progression") echo "<option SELECTED value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
else echo "<option value=\"I-iii-IV-V progression\">I-iii-IV-V progression</option>";
echo  "</select>";

echo "&nbsp;&nbsp;&nbsp;";

echo "<select name=\"prog2_menu\" onchange=\"this.form.submit();\">";

echo "<option value=\"--Specify2--\">--Specify--</option>";
if ($prog2_menu == "I-sharpIo7-ii7-sharpIIo7 progression") echo "<option SELECTED value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
else echo "<option value=\"I-sharpIo7-ii7-sharpIIo7 progression\">I-#Io7-ii7-#IIo7 progression</option>";
if ($prog2_menu == "I-sharpIo7-ii7-V7 progression") echo "<option SELECTED value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
else echo "<option value=\"I-sharpIo7-ii7-V7 progression\">I-#Io7-ii7-V7 progression</option>";
echo  "</select>";

echo "</form>";
I am trying to identify which select box has been used so that I can set all the other boxes to the 1st item but I wind up re-setting all the boxes.

hi 

I am trying to add a few line of code using fopen

It works and it adds the lines but I have multiple occurrence of this line and I would like to all be amended.

$target_line='$second = (int)substr($raw_date, 17, 2);';
$lines_to_add= '$raw_datetime =  translate_from_gregorian($raw_datetime);'. PHP_EOL.
    '$year = (int)substr($raw_datetime, 0, 4);'. PHP_EOL.
    '$month = (int)substr($raw_datetime, 5, 2);'. PHP_EOL.
    '$day = (int)substr($raw_datetime, 8, 2);'. PHP_EOL;
$config ='includes/functions/general.php';
$file=fopen($config,"r+") or exit("Unable to open file!");
$insertPos=0;  // variable for saving //Users position
 while (!feof($file)) {
    $line=fgets($file);
    if (strpos($line,$target_line)!==false) { 
        $insertPos=ftell($file);    // ftell will tell the position where the pointer moved, here is the new line after //Users.
        $newline =  $lines_to_add;
    } else {
        $newline.=$line;   // append existing data with new data of user
    }
}

fseek($file,$insertPos);   // move pointer to the file position where we saved above 
fwrite($file, $newline);

fclose($file);

 

Hi, how do I extract a substring? I just want to store "car" in a variable for other uses:

Folks,

I want to extract something from a URL, i think we need to use regex for this.

Example URL:
Code: [Select]
http://www.amazon.co.uk/gp/aw/d/B004JN01LW/ref=mp_s_a_1?qid=1305169492&sr=8-1

What we need to Extract:
So we need to extract  B004JN01LW  from the URL.

I tried to use substr() but i think its not useful for this purpose, can someone help me with Regex to extract this?

Cheers

I am using tinyMCE editor and uploading image from it.After form is submitted,it makes textarea's values as

<img width="\"65\"" height="\"66\"" alt="\\"" src="\"images/logo.gif\"">

cuz of wrong html,it is not displaying image.I tried to replace

$_POST['elm2'] = str_replace('"\"','\"',$_POST['elm2']);
$_POST['elm2'] = str_replace('\""','\"',$_POST['elm2']);

but it is not replacing.How can i correct the HTML so that i display image.

So I have a database with a bunch of dates in it. In this format 05/15/2011. And this is how I get that out.

$data = mysql_query("SELECT * FROM location ORDER BY id ASC") or die(mysql_error());

while($info = mysql_fetch_array( $data )) {
 
  $date = $info['date'];
};

echo "$date";

The resulted echo would be 05/26/2011

How do I get $date to echo out JUST 05? I'm trying to isolate the month. I think the method is using substrings, but I havent had any luck.

Thanks any help would be great!

Let's say I have the string "Bob is my friend. Bob likes to eat apples. Goodbye!".

I give a function that string, and the two strings "Bob" and "apples". It returns "Bob likes to eat apples". I seem to have trouble making this function.
If I wanted it to return "Bob is my friend. Bob likes to eat apples" that would be much simpler, but I am trying to get the smallest amount of characters between the two strings.

I tried doing this, but seem to either get stuck on an infinite loop or return the entire inputted string.
Code: [Select]
function between($strIn, $str1, $str2){
$pos2 = stripos($strIn, $str2);
$pos = 1;
$strStore = "";
while($pos>0 && $pos<$pos2){
$pos = stripos($strIn, $str1);
$strStore = substr($strin, $pos, $pos2-$pos);
$strIn = substr_replace($srtIn, $strtemp, "");
}
return $strStore;
}

What it does it finds the first occurrence of "apples" ($str1) and then keeps finding and deleting every occurrence of "Bob" ($str2) until the position of "Bob" surpasses the position of "apples".

As you can tell, it doesn't work. Could anyone help me out, or tell me what I am doing wrong?

Hello,

Does anyone know how to get a substrig by referencing other substrings around it?

Ie, my string is the following:

These are my favorite foods:
 <ul>
   <li id="1"> Pizza </li>
   <li id="2"> Burgers </li>
   <li id="three"> Hot Dogs </li>
 </ul>
I need to get the ID of each list item, i know they will always follow "<li id=".
I also need to get the text of each list item, i know they will always be before "</li>"

Thanks!

Hey all,

I have method like this:

Code: [Select]
echo tinymce_tag($post->body);

Basically the body property contains a string from database containing one or many paragraphs delimited by p tags:

Code: [Select]
<p>Hello World.</p>
<p>Goodbye World.</p>

I want to give all the paragraphs a class. This function will give the first p tag a class:

Code: [Select]
if ( ! function_exists('tinymce_tag')){
function tinymce_tag($content = ''){

$pos = strpos($content, '<p>');

if($pos !== false){
$content = substr_replace($content,' class="paragraph_styler"', 2, 0);
}
return $content;
}
}

But I am not sure how to give all the p tags in the content variable a class.

Thanks for response.
