Question about str_replace()

[MinusMyThoughts]

so, i've put all my update pages in a folder called "update" for organizational purposes......now, that's all working fine, except i'm trying to display my database content on my update pages, including the URL of pictures that my user uploads to accompany things like testimonials and article posts......i use a function with the uploading of the image to save a database entry linking to it that looks like this:

<img src="images/praisePics/img.jpg">

...the problem is that when i call that from the "update" folder, i need to use

<img src="../images/praisePics/img.jpg">

...so i had the idea to use explode("/",$pictureURL) to break it into an array that i called $pictureURL that (at least i think) should look like this:$pictureURL[0] = <img src="images$pictureURL[1] = praisePics$pictureURL[2] = img.jpg">...so i'm running str_replace('src="images','src="../images',$pictureURL) to make the changes to the URL......then i'm running the whole thing through this for() loop:

	$picture = '';	for($i = 0; $i <= count($pictureURL) - 1; $i++)	  {	  $picture = $picture . $pictureURL[$i] . '/';	  }	$picture = $picture . $pictureURL[$i];

...so the whole thing looks like this:

	$pictureURL = explode("/",$display['praisePic']);	str_replace('src="images','src="../images',$pictureURL);	$picture = '';	for($i = 0; $i <= count($pictureURL) - 1; $i++)	  {	  $picture = $picture . $pictureURL[$i] . '/';	  }	$picture = $picture . $pictureURL[$i];

...i know i'm doing something wrong, but i'm at a loss. anyone feeling helpful? thanks!love,jason

$pictureURL = explode("/",$display['praisePic']);	str_replace('src="images','src="../images',$pictureURL);	$picture = '';	for($i = 0; $i <= count($pictureURL) - 1; $i++)	  {	   	  $picture .= $pictureURL[$i];		   if ( $i < 2 )  {  $picture .= '/';}	  }	echo $picture;

Might work. The ".=" is the concatenation operator.

after a little alteration, it worked great!...here's what i'm using that is currently working:

	$pictureURL = $display['praisePic'];	$pictureURL = explode("/",$display['praisePic']);	str_replace('src="images','src="../images',$pictureURL);	$picture = '<img src="../images/';	for($i = 1; $i <= count($pictureURL) - 1; $i++)	  {	  	  $picture .= $pictureURL[$i];		if ( $i < 2 )  {  $picture .= '/';}	  }

...thanks for your help!love,jason

There's an analagous function to explode that turns an array back into a string, with a "glue" character between each array piece. You can use either implode or join. join is an alias for implode, so it's probably better to use implode.http://www.php.net/manual/en/function.implode.php

	$pictureURL = $display['praisePic'];	$pictureURL = explode("/",$display['praisePic']);	str_replace('src="images','src="../images',$pictureURL);	$picture = implode("/", $pictureURL);

i didn't have any luck with that......for some reason, it doesn't seem to be replacing anything. i think the way my host is set up is funky, though, because str_ireplace() gives me an error as a "call to undefined function."...thanks, though!love,jason

str_ireplace is only in PHP5.
