How to convert String(16) to Int(1) in php - php

Question

For instance
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}"; //this syntax works
var_dump($user_post_id); // gives String(16) '1'
$user_post_int_id = (int)$user_post_id; // change from string to int
var_dump($user_post_int_id); // gives int(1) 0, I don't know why isn't type conversion working!
echo $user_post_id; // echoes out 1
echo $user_post_int_id; //echoes out the 0
So the main problem I think is of type conversion, as I tried one more thing where String(1) is converting to int(1) with no problem but with string(16) everything blows apart and results to 0.

i got 3 suggestion 4u (on my server all works fine)
as a original with my comments:
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}"; //this syntax works
var_dump($user_post_id); // gives String(16) '1'
$user_post_int_id = (int)$user_post_id; // change to int
var_dump($user_post_int_id);
// gives int(1) 1, is not test your php/server conf!
echo $user_post_id; // echoes out 1
echo $user_post_int_id; //echoes out 1
then i advise you to try with your code, run on your server with changes:
replace $user_post_id = "{{list.user.id}}";
to $user_post_id = (int){{list.user.id}};
//hopes your php wudn't show an error
replace $user_post_int_id = (int)$user_post_id;
to $user_post_int_id = floor((int)$user_post_id);
or $user_post_int_id = ceil((int)$user_post_id);
replace $user_post_id = "{{list.user.id}}";
to $user_post_id = (int)({{list.user.id}}) + 1 ;
or plus zero, these hack sometimes works for me !
p.s. (int) can do a trick with you, php can thout that you uses hex bin or smth else. retest it twice !

You cannot use Angular expression inside a server side statements, as Angular statement runs on client side after running all server logic.
In your code:
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}" //list.user.id is a JS variable, you cannot use it in PHP.
$user_post_int_id = (int)$user_post_id; // something wrong here, you do not need this step, normally if you retrieved the code from server side.
{{ $user_post_int_id }} //this should not work
But still this blade function fails
#if(Auth::user()->id == $user_post_int_id)
do something //returns false, makes alot of sense, as again you are trying to get variables from JS and passing them to PHP scripts. This will never work.
#endif
