I want to use preg_replace to replace string with an array of identical patterns but different replacements

Question

I want to replace different patterns in a string with the identical string. The replacements is an array with different values.

Since the pattern has to be mixed, I cannot find a solution. Also because preg_replace_all doesn't exist. Does anybody have an idea?

My code:

$artikelinhoud = $simpleXml->StandaardOplossing->attributes()->ArtikelInhoud;
$arrayImages = array();
preg_match_all('<!\[(CDATA)\[\s*(.*?)\s*\]\]>', $artikelinhoud, $arrayImages);

$images = array(); 
foreach ($arrayImages[2] as $key => $image) {
$images[$key] = 'src="data:image/jpg;base64,' . $image . '"';   
}

$imagesOld = array();
$imagesOld[] = '/type="(.*?)"/';

$artikelinhoud = preg_replace($imagesOld, $images , $artikelinhoud);

So variable $imagesold is always the same. And $images is an array with different values to put between tags.

preg_replace replaces already all occurances of the pattern. But propably you're interested in preg_replace_callback() — TiMESPLiNTER

yes, but why it replaces all the patterns with $images[0] and not with $images[0], $images[1], etc? — Eric1978

Because with preg_replace() you're very limited in replacement of the matched string. But use preg_replace_callback() to have more possibillities. — TiMESPLiNTER

I'd like to post the code, but I need to see an example of what $images looks like. Does it contain $1 that substitutes something for the capture group un $imagesOld? — Barmar

images is array( [0]=> string(26464) "src="data:image/jpg;base64,/9j/4AA........) ,[1]=> string(22464) "src="data:image/jpg;base64,/9j/4AA........) it is meant to put between the <IGM> tag in HTML It needs to replace different times <IMG type="jpg"> So different images replace same patterns — Eric1978

I had a similar problem, I found this solution perfect for me.

In your code:

$artikelinhoud = $simpleXml->StandaardOplossing->attributes()->ArtikelInhoud;
$arrayImages = array();
preg_match_all('<!\[(CDATA)\[\s*(.*?)\s*\]\]>', $artikelinhoud, $arrayImages);

$images = array(); 
foreach ($arrayImages[2] as $key => $image) {
  $images[$key] = 'src="data:image/jpg;base64,' . $image . '"';   
}

$imagesOld = array_fill(0, count($images), '/type="(.*?)"/');

$artikelinhoud = preg_replace($imagesOld, $images , $artikelinhoud, 1);

Hope this helps.

Cheers!
