I am trying to replace the keyword with another keyword, but not want to replace the keyword if it starts with = (equal) sign.

For example:

$content = "This is my bag and but is =bag".
$replace = 'testing';
$find = "bag".

$ptn = '/\b' . preg_quote($find, '\b/') . '\b/';

preg_replace($ptn, $replacement, $content, $limit =2, $count=2);

But this returning: This is my testing and but is =testing

I want: This is my Testing and but is =bag

Please help me to write the correct pattern.

Thanks

Use: `$ptn = '/(?<!=)\b' . preg_quote($find, '/') . '\b/';` – anubhava Feb 17 '20 at 08:33

@anubhava It looks like working. – D Singh Feb 17 '20 at 08:39
The answers is `$processedContent = preg_replace("/(.*\b[^=])({$find})(\b.*)/", '${1}testing${3}', $content);` – asiby Feb 17 '20 at 08:54
@asiby: Try with `$content = "bag and =bag"` – Toto Feb 17 '20 at 11:45
@Toto, try it with `$processedContent = preg_replace("/(.*\b[^=])*({$find})(\b.*)/", '${1}testing${3}', $content);`. – asiby Feb 18 '20 at 19:00
