PHP replace tags with dynamic values including IF condition -

replacing dynamic values in php can achieved using code this:

$replace = array('{cover_amt}','{liability_amt}','{total_amt}'); $with = array('90', '90', '0');  $mystring = 'this cover amt : {cover_amt} . liablity amount :     {liability_amt} . total amount : {total_amt}';  echo str_replace($replace, $with, $mystring); 

output:

this cover amt : 90 . liablity amount : 90 . total amount : 0 

this give correct output.

but when value 0 should not displaying text itself. case, total amount should not displayed @ 0.

check if condition not great solution mess code if there lots of ‘0’s .

if there around 100 array elements, impossible check each values. solution can used number of data inputs great.

any 1 great idea achieve this.

thanks.

why not trying this:

<?php $replace = array('{cover_amt}','{liability_amt}','{total_amt}', 'this total amount : 0'); $with = array('90', '90', '0','');  $mystring = 'this cover amt : {cover_amt} . liablity amount :     {liability_amt} . total amount : {total_amt}';   echo str_replace($replace, $with, $mystring);  ?> 

it delete last part if total amount 0.

acording edited question:

<?php  $replace = array('{cover_amt}','{liability_amt}','{total_amt}'); $with = array('0', '90', '0');  $mystring = 'this cover amt : {cover_amt} . liablity amount :     {liability_amt} . total amount : {total_amt}';  $mystring = str_replace($replace, $with, $mystring); $mystring_array = explode("this is",$mystring); foreach($mystring_array $mystring_sliced) {  $pattern = '/(\.?)(this )(.*?) 0(\s?)(\.?)/i'; $replacement = ''; if($mystring_sliced) echo preg_replace($pattern, $replacement, "this ".$mystring_sliced); } ?>
