I have a string:
"imagens":["upload/7057c705298193c513f07fbb8fbe2856.jpg", "upload/30c2dbcd5c890e763fab6ccfa63ab24c.jpg", "upload/40f4af351cfa1d01ca2e468965d28626.jpg", ]
And I want to delete the last comma of it, leaving it like this:
"imagens":["upload/7057c705298193c513f07fbb8fbe2856.jpg", "upload/30c2dbcd5c890e763fab6ccfa63ab24c.jpg", "upload/40f4af351cfa1d01ca2e468965d28626.jpg"]
How to do it?
// Remove os dois últimos caracteres
$str = substr($str, 0, strlen($str)-2);
// Acrescenta de volta o ]
$str .= ']';
You can do this with the function str_replace
$string = '"imagens":["upload/7057c705298193c513f07fbb8fbe2856.jpg", "upload/30c2dbcd5c890e763fab6ccfa63ab24c.jpg", "upload/40f4af351cfa1d01ca2e468965d28626.jpg", ]';
echo str_replace(', ]', ']', $string);
The result will be:
"imagens":["upload/7057c705298193c513f07fbb8fbe2856.jpg", "upload/30c2dbcd5c890e763fab6ccfa63ab24c.jpg", "upload/40f4af351cfa1d01ca2e468965d28626.jpg"]
See the following code snippet that removes the comma with or without space before the bracket.
<?php
/*A string que vc forneceu*/
$texto = '"imagens":["upload/7057c705298193c513f07fbb8fbe2856.jpg", "upload/30c2dbcd5c890e763fab6ccfa63ab24c.jpg", "upload/40f4af351cfa1d01ca2e468965d28626.jpg", ]';
/*Limpa String*/
echo preg_replace("/,(\s{1,}|)]/", "]", $texto);
?>
