Sample code:
<code><span>$a</span> = <span>'10'</span>; var_dump(gettype(<span>$a</span>)); settype(<span>$a</span>,<span>'int'</span>); var_dump(gettype(<span>$a</span>));</code>
The output results at this time are: string, interger
But if:
<code><span>$a</span> = <span>10</span>; var_dump(gettype(<span>$a</span>)); settype(<span>$a</span>,<span>'int'</span>); var_dump(gettype(<span>$a</span>));</code>
The output results at this time are all single quotes in interger

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });The above introduces the single quotes in PHP (conversion between int type and string type), including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
