Help - parse text file, find keyword

[lufa20]

I am looking for a way to parse a file that contains a lot of text that is comma separated, yet it is not a csv. 

What i want is to find a keyword then echo that keyword and a few characters after that keyword, then look for another keyword and echo that keyword and some characters after that keyword...etc.

 

Can someone point me in the right direction please?

Take a look at ths php function: http://www.php.net/manual/en/function.preg-match.php

Use a regex to find the matches and do what you want with that.

Ok here is what I have and what I need it to look like:

 

Sample file:

 

{"RubricCriterion":[{"num":1,"value":"25","previous_version":null,"position":1,"name":"Writing","description":null,"rubric":352600,"criterion_scales":[10985652,10985648,10985644,10985640],"id":3423222},{"num":2,"value":"25","previous_version":null,"position":2,"name":"Grammar","description":null,"rubric":352600,"criterion_scales":[10985651,10985647,10985643,10985639],"id":3423223},{"num":3,"value":"25","previous_version":null,"position":3,"name":"Punctuation","description":null,"rubric":352600,"criterion_scales":[10985650,10985646,10985642,10985638],"id":3423224},{"num":4,"value":"25","previous_version":null,"position":4,"name":"Spelling","description":null,"rubric":352600,"criterion_scales":[10985649,10985645,10985641,10985637],"id":3423225}],"Rubric":[{"cv_loaded":"1","criterion":[3423222,3423223,3423224,3423225],"assignments":[],"id":352600,"papers_scored":"0","owner":1006900964,"criterion_scales_all":[10985652,10985648,10985644,10985640,10985651,10985647,10985643,10985639,10985650,10985646,10985642,10985638,10985649,10985645,10985641,10985637],"name":"MyRubric","deleted":0,"description":null,"distribute_criterion_percentage":0,"total_points":null,"scoring_method":2,"scale_values":[3343228,3343229,3343230,3343231],"rubric_group":null}],"RubricScale":[{"num":1,"value":"25","position":1,"name":"Not Acceptable","id":3343228,"rubric":352600},{"num":2,"value":"50","position":2,"name":"Beginner","id":3343229,"rubric":352600},{"num":3,"value":"75","position":3,"name":"Competent","id":3343230,"rubric":352600},{"num":4,"value":"100","position":4,"name":"Proficient","id":3343231,"rubric":352600}],"RubricCriterionScale":[{"scale_value":3343228,"value":"0","criterion":3423222,"id":10985652,"description":"poor writing"},{"scale_value":3343229,"value":"0","criterion":3423222,"id":10985648,"description":"begineer writing"},{"scale_value":3343230,"value":"0","criterion":3423222,"id":10985644,"description":"competent writing"},{"scale_value":3343231,"value":"0","criterion":3423222,"id":10985640,"description":"proficient writing"},{"scale_value":3343228,"value":"0","criterion":3423223,"id":10985651,"description":"poor grammar"},{"scale_value":3343229,"value":"0","criterion":3423223,"id":10985647,"description":"beginner grammar"},{"scale_value":3343230,"value":"0","criterion":3423223,"id":10985643,"description":"competent grammar"},{"scale_value":3343231,"value":"0","criterion":3423223,"id":10985639,"description":"proficient grammar"},{"scale_value":3343228,"value":"0","criterion":3423224,"id":10985650,"description":null},{"scale_value":3343229,"value":"0","criterion":3423224,"id":10985646,"description":null},{"scale_value":3343230,"value":"0","criterion":3423224,"id":10985642,"description":null},{"scale_value":3343231,"value":"0","criterion":3423224,"id":10985638,"description":null},{"scale_value":3343228,"value":"0","criterion":3423225,"id":10985649,"description":null},{"scale_value":3343229,"value":"0","criterion":3423225,"id":10985645,"description":null},{"scale_value":3343230,"value":"0","criterion":3423225,"id":10985641,"description":null},{"scale_value":3343231,"value":"0","criterion":3423225,"id":10985637,"description":null}]}

 

 

 

Desired Output (i will format the html to make it pretty)

Use this http://www.php.net/manual/en/function.json-decode.php to get the result out of that string. That is JSON object that you can use.

[lufa20]

why does it work when I insert it into $string and it doesn't when I don't

 

<?
$file = "rbc/$_GET[parse]";
$string = json_decode(file_get_contents($file, true));

foreach ($string->RubricCriterion as $rubric) {
    echo $rubric->name;
}
?>

EDIT [ignace]: I accidently edited your post mistaken it for quoting you so the wording may be different, my apologies Edited April 26, 2013 by ignace

[ignace]

you mean like this?

 

<?php
$file  = "rbc/" . basepath($_GET['parse']);

if (!file_exists($file)) {
  printf("file %s does not exist", $file);
  exit;
}

foreach (json_decode(file_get_contents($file, true))->RubricCriterion as $rubric) {
    echo $rubric->name;
}
