var_export()¶
var_export() is a PHP native function that produces a representation of the passed data as PHP code.
var_export() is used for cache, by storing an intermediate result for later inclusion. var_export() is also used for storing PHP data, and later accessing them in their current form: it by-pass the process of serializing/unserializing by using PHP as the serialization itself.
var_export() is usually replaced by print_r(), var_dump() or other adapted functions when it is immediately displayed, during development session.
<?php
print var_export(1); // 1
print var_export(abc); // 'abc'
$a = [1, 3, 4];
$a[] = 5;
print var_export($a); //
class X {
public string $p = 'yes';
}
$x = new X();
$x->p = 'PHP rocks';
print var_export($a); //
?>
