preg_replace only replaces first occurrence then skips to next line [duplicate]
Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced.
What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content:
$resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content);
Does anyone know a solution for why it only replaces the first match per line?
Try:
$resource_content = preg_replace('#(url\((\'|")?)(.*?)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content);
That will keep the (.*)
term from matching "too much" content.
make an example - If your $variable is:
STARTING
FIRSTT AAA
SECONDD AAA
1) if you implement this function:
$variable = preg_replace('/STARTING(.*)AAA/', 'REPLACING_STRING', $variable);
it changes everything (from the STARTING to the latest AAA) and the result is:
REPLACING_STRING
2) if you use:
$variable = preg_replace('/STARTING(.*?)AAA/', 'REPLACED_STRING', $variable);
The Result is:
REPLACING_STRING
SECOND AAA
