[SOLVED] getting contents between tags in string and output them one by one?

[Sam Granger]

Hey!

 

I have a pdf class, and I can use it to output images. I want to get info from the database. The content could look like this for example:

text text text, more text [image]hello.jpg[/image] haha hello [thumb]hi.gif[/thumb]. haha more text

 

Anyway, you get the point .

 

How do I get the contents out of the tag and put them into images? I think array? or?

 

I need to use a seperate code for text and images to generate the pdf.

 

For text:

$pdf->ezText("$title", 22);

 

And for images:

$pdf->ezImage('http://www.domain.com/logo.jpg', '0', '150', 'none', 'left');

 

for each image.

 

Help!

 

Do I use preg_match?

Just to make it clear, I don't need to input the images inbetween the text, I will strip the text for the tags+filenames, output that and then will output all images at end.

Hope someone can answer this

This should do what you need. It will strip out all the tags and populate them into an array. It won't handle nested tags though. I also added in some basic whitespace handling to help make the returned text look better.

 

<?php
  function matchCallback ( $matches ) {
    global $tags;
    list(,$tag,$contents,$suffix) = $matches;

    //Add Tag
    if(!isset($tags[$tag])) $tags[$tag] = array();
    $tags[$tag][] = $contents;
    
    //Make replacement
    $rVal = '';
    return (preg_match('/[a-zA-Z0-9]/',trim($suffix)))
      ? ' '.trim($suffix) //Found a charachter, add a space
      : trim($suffix); //Found something else, no space
  }

  $text = "text text text, more text [image]hello.jpg[/image] haha hello [thumb]hi.gif[/thumb]. haha more text";
  $tags = array();
  $text = preg_replace_callback('/\s*\[(\w+)\](.+?)\[\/\1\](\s*.?)/',matchCallback,$text);
  print_r($tags);
  print $text;
?>

Awesome that works! How would I go about echoing the tag contents one by one in a loop/while statement?

<?php
...
  $text = "text text text, more text [image]hello.jpg[/image] haha hello [thumb]hi.gif[/thumb]. haha more text";
  $tags = array();
  $text = preg_replace_callback('/\s*\[(\w+)\](.+?)\[\/\1\](\s*.?)/',matchCallback,$text);

  //Go through all of them
  foreach($tags as $tagname=>$items){
    print "<b>{$tagname}</b><ul>";
    foreach($items as $item)
      print "<li>{$item}</li>";
  }

  //Just image tags
  if(is_array($tags['image'])){
    foreach($tags['image'] as $item)
      $pdf->ezImage($item, '0', '150', 'none', 'left');
  }
?>
