Error message for processing big data - php

Question

I have a problem when i process files in php. When processing small files, it can be seen the output. But, when large files it shows the warning like this :
PHP Fatal error: Out of memory (allocated 1068498944) (tried to allocate 133955584 bytes) in C:\xampp\htdocs\ujian_online\application\views\data_soal\view_proses.php on line 644
we can see the code like this :
<?php
$no_urut = 0;
//print_r($array_query_simantic_reletedness);
foreach ($val_simantic_reletedness as $doc_simantic_word) {
foreach ($array_query_simantic_reletedness as $text_simantic_current_key => $text_simantic_current_val) {
//get fix val
$status = 0;
$spe = 0;
$sr = 0;
if ($text_simantic_current_key == $doc_simantic_word) {
$status++;
$spe = 1;
}
$where_get_kamus = array('kata' => $text_simantic_current_key);
$get_kamus = $this->master->find_data($where_get_kamus, 'tb_kamus')->row_array();
// print_r($get_kamus);
//split kamus by ';'
$kamus_synonim = explode(';', $get_kamus['synonim']);
//split kata by '.'
foreach ($kamus_synonim as $key_word_split => $val_word_split) {
$kata_current_kamus = explode(';', $val_word_split);
//print_r($kata_current_kamus);
foreach ($kata_current_kamus as $key_current_word_doc => $val_current_word_doc) {

$word_split_doc = explode('.', $val_current_word_doc);

continue;
}
if (isset($word_split_doc[1])) {
$word_split_slash = explode('|', $word_split_doc[1]);
}
// print_r($word_split_slash);
// ---- foreach for checking ---
foreach ($word_split_slash as $val_current_word_check) {
//print_r($val_current_word_check);
$val_current_word_check = str_replace(' ', '', $val_current_word_check);
$val_current_word_check = str_replace("\r", '', $val_current_word_check);
$val_current_word_check = str_replace("\t", '', $val_current_word_check);

if ($doc_simantic_word == strtolower($val_current_word_check)) {

// penentuan dmax
$where_get_spe_check = array('kata' => $doc_simantic_word);
$get_word_spe = $this->master->find_data($where_get_spe_check, 'tb_kamus')->row_array();
if ($get_kamus['dmax'] > $get_word_spe['dmax']) {
$dmax_spe = $get_kamus['dmax'];
} else {
$dmax_spe = $get_word_spe['dmax'];
}
//count spe
$spe = $get_kamus['dmax'] / $dmax_spe;
}
}
//---- end foreach for checking ----------------
//echo '<br>';
}
}
$no_urut++;
if ($status > 0) {
$val_view = 1;
} else {
$val_view = 0;
$spe = 0;
}
$sr = $spe * $val_view;
echo "
<tr>
<td>$no_urut</td>
<td>$text_simantic_current_key " . '=' . " $doc_simantic_word</td>
<td>$val_view</td>
<td>$spe</td>
<td>$sr</td>

";
// echo '||';echo $no_urut;echo '|'; echo $text_simantic_current_key ; echo '=' ;echo $doc_simantic_word;echo '|'; echo $val_view;echo '|'; echo $spe;echo '|'; echo $sr;
}
}//end simantic word doc
?>
and i give the highlight for line 644 is
> echo "
<tr>
<td>$no_urut</td>
<td>$text_simantic_current_key " . '=' . " $doc_simantic_word</td>
<td>$val_view</td>
<td>$spe</td>
<td>$sr</td>
</tr>
> ";
But when i check my code in https://phpcodechecker.com/
i have the different notice like this :
Error: There is 1 more opening parenthesis '(' found
This count is unaware if parenthesis are inside of a string
and we can see the code :
$get_data_tema = $this->master->find_data(array('id_tema'=>$key_val_final),'tb_tema')->row_array();
echo 'nama tema " <b>'.$get_data_tema['nama'].'</b>"';
}
$array_post_input = array('text_soal'=> $data_post['text_soal'],
'a' =>$data_post['a'],
'b' =>$data_post['b'],
'c' =>$data_post['c'],
'd' =>$data_post['d'],
'e' =>$data_post['e'],
'answer' =>$data_post['answer'],
'guru_id'=> $this->session->userdata('id_current'),
'tema_id'=>0,
'mapel_id' =>$data_post['mapel_id'],
'gbrsoal' =>$data_post['gbrsoal'],'label_id'=>0,
);
$this->master->insert_data('tb_soal',$array_post_input);
I am using xampp version v3.2.2 and windows 8.1, RAM 8 GB with 6,94 useable, PHP version 5.6.15 with codeigniter framework and i have set in memory limit inside php.ini 51200000000000 M. So, what should i do to fix my problem? Which line must be i repair it? Thanks.

Answer 1

Solution for the first problem: With a large amount of data, the printing process can be very resource expensive. So, save the printable parts into an array and print them once, after all foreach iterations are finished. Note: look for $results in my code.
<?php
$results = [];
$no_urut = 0;
foreach ($val_simantic_reletedness as $doc_simantic_word) {
foreach ($array_query_simantic_reletedness as $text_simantic_current_key => $text_simantic_current_val) {
//...
$sr = $spe * $val_view;
$results[] = "<tr>
<td>$no_urut</td>
<td>$text_simantic_current_key " . '=' . " $doc_simantic_word</td>
<td>$val_view</td>
<td>$spe</td>
<td>$sr</td>
</tr>";
}
}
echo implode('', $results);
Solution for the second problem (if I understood it correctly): remove the "}" character which appears right after the line
echo 'nama tema " <b>' . $get_data_tema['nama'] . '</b>"';
Good luck.
