php - about regex, you find {else} and allow nested -
i created pattern: {if ([^}]*)}((?:[\w\s]+[^}]*)){\/if} but have done long time ago now, pattern is, example: {if $module=admin} {/if} but want find: {if $module=admin} {else} {/if} as far possible find both same pattern. any ideas? thank :) /{if ([^}]+)}([\w\w]*?)(?:{else}([\w\w]*?))?{\/if}/g {if literal text. ([^}]+) if condition : 1 or more non-closing-curly-brace ( } ) characters, captured. } literal text. ([\w\w]*?) inside if : 0 or more characters. match until next part found. (very inefficient; can rewrite make more performant.) (?:{else}([\w\w]*?))? optional group. {else} else : literal text. ([\w\w]*?) inside else : 0 or more characters. match until next part found. (very inefficient; can rewrite make more performant.) {\/if} closing : literal text.
