Explode txt file into multidimensional array - php

Question

I have a .txt file that looks like the one below:
Test = 10849831 = August 6, 2013:
56cake = 0 = August 6, 2013:
Wwe = 812986192 = August 6, 2013:
I want to explode the file above to make an array that looks like the one below:
Array
(
[Test] => Array
(
[0] => 10849831
[1] => August 6, 2013
)
[56cake] => Array
(
[0] => 0
[1] => August 6, 2013
)
[Wwe] => Array
(
[0] => 812986192
[1] => August 6, 2013
)
)
How can I accomplish this? I've already tried using something like explode(":", $data) but I don't know how to use it to do what I want above. I'm fairly new with PHP.

Answer 1

Just a little bit of array iteration does the trick with: explode, array_map, trim, isset and foreach.
PHP Example
$txt = <<<DOC
Test = 10849831 = August 6, 2013:
56cake = 0 = August 6, 2013:
Wwe = 812986192 = August 6, 2013:
DOC;
$Output = array();
$Lines = explode(":", $txt);
foreach($Lines as $line) {
$Rows = array_map('trim', explode(" = ", $line));
if(!isset($Rows[0], $Rows[1], $Rows[2])) continue;
$Output[$Rows[0]] = array($Rows[1], $Rows[2]);
}
print_r($Output);
PHP Code Output
Array
(
[Test] => Array
(
[0] => 10849831
[1] => August 6, 2013
)
[56cake] => Array
(
[0] => 0
[1] => August 6, 2013
)
[Wwe] => Array
(
[0] => 812986192
[1] => August 6, 2013
)
)
The Code Explained
Break up the lines with explode(":", $txt)
Loop through each line and break up each section by = again using explode
Use array_map to cycle each value and remove whitespace
Check to ensure we have 3 values with isset, if not, then skip the iteration
Push our collected values into the output array

Answer 2

Something like this?
<?php
// Sample text data
$text = 'Test = 10849831 = August 6, 2013:
Test = 10849831 = August 6, 2013:
56cake = 0 = August 6, 2013:
Wwe = 812986192 = August 6, 2013:';
$text = explode( PHP_EOL, $text ); // split by lines using linebreaks
// $text = explode( ":", $text ); // you can also split by lines with ':'
$arr = array(); // Our array which holding the output
// print_r( $text );
foreach( $text as $line ) { // loop through lines
$line = array_map( "trim", explode( "=", $line ) ); // split by '=' sign and do 'trim'
// print_r( $line );
if ( count( $line ) === 3 ) {
$key = strtolower( $line[0] ); // make the key lowercase (case insensitive)
$val1 = $line[1];
// process the date and remove day from date
$val2 = trim( $line[2], ":" ); // remove ':' from the end of date
$val2 = array_map( "trim", explode( " ", $val2 ) ); // split by space sign and do a 'trim'
$val2 = $val2[0]." ".$val2[2]; // join year and month parts
if ( isset( $arr[$key] ) ) { // check if the key already exists
// key exists, push new values
array_push( $arr[$key], $val1, $val2 );
continue; // key exists so continue the loop
}
// key doesn't exists in array so add the values
$arr[$key] = array( $val1, $val2 );
}
}
// there is an altwernate way to remove duplicate values using 'array_unique'
// uncomment below code if you dont want duplicate values
/*if ( !empty( $arr ) ) {
$arr = array_map( "array_unique", $arr ); // remove duplicate values from array using 'array_unique'
}*/
print_r( $arr );
?>
Here is the list of functions which i used in my code and link to those functions documentation
explode
array_map
trim
count
strtolower
isset
array_push
array_unique

Answer 3

Try to re-use this code:
<?php
echo '<pre>';
$result = array();
$string = 'Test = 10849831 = August 6, 2013';
$temp1 = explode("=", $string, 2);
print_r($temp1);
/*
Array
(
[0] => Test
[1] => 10849831 = August 6, 2013
)
*/
$key = $temp1[0];
$result[$key] = explode("=", $temp1[1]);
print_r($result);
/*
Array
(
[Test ] => Array
(
[0] => 10849831
[1] => August 6, 2013
)
)
*/
?>

Answer 4

$chunks = explode(':', $text);
$out = array();
foreach ($chunks as $key => $value){
$parts = explode('=', $value);
if (count($parts) == 3){
$out[trim($parts[0])] = array(trim($parts[1]), trim($parts[2]));
}
}
print_r($out);

Answer 5

You have use explode like this:
<?php
//
//Test = 10849831 = August 6, 2013:
//56cake = 0 = August 6, 2013:
//Wwe = 812986192 = August 6, 2013:
function read_data_file( $file ) {
$file_open = fopen( $file , 'r' );
$file_data = fread( $file_open , filesize( $file ) );
fclose( $file_open );
return $file_data;
}
$result_read = read_data_file('/home/josecarlos/Desktop/test.txt');
$result_explode = explode("\n", $result_read );
$final_result = array();
foreach ($result_explode as $key => $cursor){
$explode = explode("=", $cursor );
if (isset($explode[0]) && $explode[0] != ''){
$final_result[trim($explode[0])] =array (trim($explode[1]),trim($explode[2])) ;
}
}
var_dump($final_result);
The result is:
array(3) {
'Test' =>
array(2) {
[0] =>
string(8) "10849831"
[1] =>
string(15) "August 6, 2013:"
}
'56cake' =>
array(2) {
[0] =>
string(1) "0"
[1] =>
string(15) "August 6, 2013:"
}
'Wwe' =>
array(2) {
[0] =>
string(9) "812986192"
[1] =>
string(15) "August 6, 2013:"
}
}
