eregi and eregi replace

[Nel]

Hi all,

I am struggling with understanding a small eregi problem in php4.

My code:
<?PHP
$htmlsource = '<img src="pics/hotdog.gif"> text text <img
src="pics/silly%20sausage .gif"> ';
eregi('(=")(pic s/)([0-9a-zA-Z%/ ]+.[a-zA-z]..)(")',$htmlso urce,$imagesint ext);
?>

var_dump gives this, so I know it's working
Outputs
array(5) {
[0]=>
string(18) "="pics/hotdog.gif""
[1]=>
string(2) "=""
[2]=>
string(5) "pics/"
[3]=>
string(10) "hotdog.gif "
[4]=>
string(1) """
}

What I am trying to do is replace all images in the format ="pics/image.jpg"
with "image.jpg" and at the same time make a list of the files image.jpg.
The problem is how to pick up ALL the occurances, not just the first???

Also how to use replace to remove the pics/ bit of the string.

Thanks,

Nel.

preg_match_all( ). preg_match is described as an alternative to ereg()
and it stops searching after finding one match, so I assume ereg()
stops then too.

Replace them with the zero string. preg_replace().

Be aware that . matches any character: escape it with a \ if you want a
dot.
Also, the range A-z includes [\]^_` along the way. were you trying for this?
eregi('(=")(pic s/)([0-9a-zA-Z_\-%/ ]+\.[jpgifpnJPGIFPN]{3})(")',$htmls ource,$imagesin text);
BTW, you should not allow spaces (%20) in filenames on a web site.

Try to tinker with preg_grep?

yeah, both are equally non-functional.
I think what Jim intended was

eregi('(=")(pic s/)([0-9A-Z_/\ %-]+\.[fgijnp]{3})(")'
,$htmlsource
,$imagesintext) ;
But thare's no law that images must have filenames that match that.

This: <img src="randompic. 001.php">
is valid if the PHP sets content-type and emits a correctly formed inage...
Bye.
