Question

I need your help guys to replace $ as char.
It seems that $ is ending the line in preg replace and i want to replace “$” char to “;$”

I had made the code:

$search = array(
"/\$/",


    $replace = array(
";$",
    echo preg_replace($search,$replace,"example $variable to replace");

What i made wrong?

According to RegexBuddy, the following should work:

$result = preg_replace('/\$/', ';$', $subject);

Your problem has to do with the use of double quotes instead of single quotes in your source string. Try

$result = preg_replace('/\$/', ';$', 'example $variable to replace');

to avoid variable interpolation in the source string. Or escape the $ in your string:

$result = preg_replace('/\$/', ';$', "example \$variable to replace");
