To obtain image info

[christa]

$search = array(

'{\[quote\](\r\n|\r|\n)*(.+)\[/quote\]}siU',
'{\[img\](\r\n|\r|\n)*((http)://([^;<>\*\(\)"\s]+)|[\w/\\\._\- ]+)\[/img\]}siU'
);
$replace = array(
'<b>\\2</b>',
'<img src="\\2"  alt="img" />'
);
$mytext = preg_replace($search, $replace, $mytext);

 

I need to obtain the size and dimensions of image found in replace array using getimagesize(): how can I do?

The image in the code above is \\2

regards

Use preg_replace_callback and a function to do the replacing for that one tag.

i've edited as:

 

function imgsize($myimg){
return getimagesize($myimg);
}

$search = array(
'{\[quote\](\r\n|\r|\n)*(.+)\[/quote\]}siU',
'{\[img\](\r\n|\r|\n)*((http)://([^;<>\*\(\)"\s]+)|[\w/\\\._\- ]+)\[/img\]}siU'
);
$replace = array(
'<b>\\2</b>',
'' . imgsize(\\2) . '<img src="\\2"  alt="img" />'
);
$mytext = preg_replace_callback($search, $replace, $mytext);

 

Now i obtain this result:

 

Warning: getimagesize(\2): failed to open stream: No such file or directory...

Warning: preg_replace_callback(): Requires argument 2, 'Array', to be a valid callback in...

Try reading a little more carefully. And try using php tags:

function replaceimg($matches) {
    return "matches[0]=" . $matches[0] . ", matches[1]=" . $matches[1] . ", matches[2]=" . $matches[2];
}

// simple
$search = array(
'{\[quote\](\r\n|\r|\n)*(.+)\[/quote\]}siU'
);
$replace = array(
'\\2'
);
$mytext = preg_replace($search, $replace, $mytext);

// complex
$mytext = preg_replace_callback(
    '{\[img\](\r\n|\r|\n)*((http)://([^;\*\(\)"\s]+)|[\w/\\\._\- ]+)\[/img\]}siU',
    "replaceimg",
    $mytext
);

i've tried your code but it just returns the path to image and not the width and height:

 

matches[0]= , matches[1]=, matches[2]=http://localhost/app/images/stuff.gif
