preg_replace question

<img src="abc.jpg">

I want to replace abc.jpg with ./abc.jpg, so that <img src="./abc.jpg">

Notes

1) image file may start with digit, eg:123.jpg

2) src does not always follow img, eg: <img width="125" src="abc.jpg" height="456">

Any idea on how to do it?

Thanks,

Try:
$text = preg_replace('/src="([^"]+)"/i', 'src="./\1"', $text)

hrenst42's suggestion is exactly what you've requested, but I'll point out additional things:

 1) If you only want to match images that don't start with ./ already then you need to do: /src="[^./]+([^"]+)"/i
 2) You should really use $1 as it is preferred to \1.


$text = preg_replace('/src="[^./]+([^"]+)"/i', 'src="./$1"', $text)
