QUACK Posted March 21, 2006 Share Posted March 21, 2006 I created a template class in Python worked perfect. I decided to convert it to PHP.It works as expected execpt one thing. When I do a loop and assign the block it counts backwards. Ill explaine ...[code]<?php########################################################## FILENAME: template.php# COPYRIGHT: (C) 2006, Kyle King (aibotca@yahoo.ca )################################################################################################## Class: Template# 1: set_file.# 2: assign_vars.# 3: assign_block.# 4: delete_block.# 5: parse.########################################class Template{ var $new_tpl; ######################################## # Function: set_file # 1: template, string. ######################################## function set_file ( $template ) { # Set new_tpl to the contents of $template $this->new_tpl = file_get_contents ( $template ); } ######################################## # Function: assign_vars # 1: array, array. ######################################## function assign_vars ( $array ) { # Loop though the array. foreach ( $array AS $key => $value ) { # Replace the key with the value in new_tpl. $this->new_tpl = str_replace ( '{' . $key .

'.' . $key .

See assign_block in the PHP code thats what does the block :(Thanks Quote Link to comment https://forums.phpfreaks.com/topic/5387-loop-gone-backwards/ Share on other sites More sharing options...

wickning1 Posted March 21, 2006 Share Posted March 21, 2006 I'll try and illustrate what's happening.<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->you run assign_block and it does this:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 0<br />Run it again and you get:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 1<br />Value: 0<br />Run it again and you get:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 2<br />Value: 1<br />Value: 0<br />Run delete_block and you get:Value: 2<br />Value: 1<br />Value: 0<br />Now I don't know exactly what you're shooting for but you could fix it by printing the values above the block:[code] function assign_block ( $block_name, $array ) ... # Replace keys with old keys + block in new_tpl. $this->new_tpl = str_replace ( $match[ 0 ], $block . $match[ 0 ], $this->new_tpl ); }[/code] Quote Link to comment https://forums.phpfreaks.com/topic/5387-loop-gone-backwards/#findComment-19236 Share on other sites More sharing options...
QUACK Posted March 21, 2006 Author Share Posted March 21, 2006 ah $block . $match[ 0 ] worked >.< all i had to do was switch it haha thanks very muchit does:Value: 0Value: 1Value: 2:) and ur statement was correct, it leave the block there and adds more too it until it deleted, simpel and works.
