search.php

$lines_array = file('sample.yml'); $search_string = "s1value1"; foreach($lines_array $line) { if(strpos($line, $search_string) !== false) { list(, $new_str) = explode(":", $line); $new_str = trim($new_str); } }

display.php

<form action="edit_value.php" method="post"> <td>s1value1:</td> <td>value:<input type="text" name="input1" value=<?php echo "$new_str"; ?>><input type="submit" name="submit" value="save"></td> </form>

but in display.php want able edit what's in input textbox , save file

(have no thought how that)

edit_value.php

here sample input file. i'm using .yml, cannot alter that.

sample.yml

service1: s1value1: 1 s1value2: 2 service2: s2value1: 1 s2value2: 2

assuming have @ moment ' one' value. can utilize preg_replace quite simple pattern.

$str = ' one'; $str = preg_replace('/([ ]){1}([a-z]){3}/', ' two', $str);

on pattern ([ ]){1}([a-z]){3}

([ ]){1} means preceeded 1 whitespace , ([a-z]){3} 3 lowercase letters in alphabet between or a z.

after comma ' two' actual replacement. can want. , 3rd target replacing.

ps: im not in regex please right me if im wrong
