i’working on a project php/twig and i got problem in my template while calling the split function of Twig
here is my admin.twig
{% set safeties = ["allg", "labor", "s1"] %}
{% set suArrRequire = ("1" ~ data.pflichtSU)|split('') %}
{% for safety in safeties %}
<div class="col-xs-4 col-sm-3">
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary radio-inline {% if suArrRequire[loop.index0] == 1 %}active{% endif %}" for="yes{{ loop.index0 }}">
<input type="radio" name="data[suRequire][{{ safety }}]" id="yes{{ loop.index0 }}" value="1" autocomplete="off" {% if suArrRequire[loop.index0] == 1 %}checked{% endif %}><span class="tr" key="yes"></span>
</label>
<label class="btn btn-secondary radio-inline {% if suArrRequire[loop.index0] == 0 %}active{% endif %}" for="no{{ loop.index0 }}">
<input type="radio" name="data[suRequire][{{ safety }}]" id="no{{ loop.index0 }}" value="0" autocomplete="off" {% if suArrRequire[loop.index0] == 0 %}checked{% endif %}><span class="tr" key="no"></span>
</label>
</div>
</div>
{% endfor %}
</div>
and here is the function from Twig class CoreExtension.php:
function twig_split_filter(Environment $env, $value, $delimiter, $limit = null)
{
if (strlen($delimiter) > 0) {
return null === $limit ? explode($delimiter, $value) : explode($delimiter, $value, $limit);
}
if ($limit <= 1) {
return preg_split('/(?<!^)(?!$)/u', $value);
}
$length = mb_strlen($value, $env->getCharset());
if ($length < $limit) {
return [$value];
}
$r = [];
for ($i = 0; $i < $length; $i += $limit) {
$r[] = mb_substr($value, $i, $limit, $env->getCharset());
}
return $r;
}
public function getFilters(): array
{
return [
// formatting filters
new TwigFilter('date', 'twig_date_format_filter', ['needs_environment' => true]),
new TwigFilter('date_modify', 'twig_date_modify_filter', ['needs_environment' => true]),

new TwigFilter('nl2br', 'nl2br', ['pre_escape' => 'html', 'is_safe' => ['html']]),
new TwigFilter('spaceless', 'twig_spaceless', ['is_safe' => ['html']]),
// array helpers
new TwigFilter('join', 'twig_join_filter'),
new TwigFilter('split', 'twig_split_filter', ['needs_environment' => true]),

// iteration and runtime
new TwigFilter('default', '_twig_default_filter', ['node_class' => DefaultFilter::class]),
new TwigFilter('keys', 'twig_get_array_keys_filter'),
];
