String processing

[markyoung1984]

Hi,

 

I have the following string:  <img src="test.jpg" height="200" width="300" alt="Product image">

 

I have been using some of the string processing functions within PHP but just can't seem to get what I want and wondered if anyone can help!

 

I want test.jpg to be assigned to $path, 200 to be assigned to $height and 300 to be assigned to $width.  The lengths of all these variables may change, e.g. height could be 1000.  Any ideas?

$filename = $_POST[filename];

$height = $_POST[height];

$width = $_POST[width];

 

<img src="$filename" height="$height" width="$width" alt="Product image">

 

use POST as an example

dont know if this would help you

 

<?PHP
$data = "<img src='test.jpg' height='200' width='300' alt='Product image'>";
$pieces = explode("'", $data);

echo "Image name: " . $pieces[1];
echo "<br>";
echo "Width: " . $pieces[3];
echo "<br>";
echo "Height: " . $pieces[5];
echo "<br>";
echo "Alt Tag: " . $pieces[7];
echo "<br>";
?>

 

 

This outputs

 

Image name: test.jpg

Height: 200

width: 300

Alt Tag: Product image

I don't know where you getting $width $height $path from, but I suspect you want to input them somewhere and resize the image accordingly, in that case, as mention above use POST or GET,

 

then retrieve these values and run some conditional:

if(isset($_GET['width'])){$width = $_GET['width'];}else{$width = "300px";}
if(isset($_GET['height])){$height = $_GET['height'];}else{$height = "200px";}
if(isset($_GET['path'])){$path = $_GET['path'];}else{$path = "test.jpg";}

echo "<img src='".$path."'   width='".$width."' height='".$height."' />";

 

there is probably better ways to do this, but this is one of quite a few, remember to use quotations wisely, hope it helps

try

<?php
$string = '<img src="test.jpg" height="200" width="300" alt="Product image">';
preg_match_all('/(\S+)="([^"]+)"/', $string, $out);
$out = array_combine($out[1], $out[2]);
print_r($out);
?>
