无法通过PHP执行.sh文件

Question

我正在尝试通过.sh文件备份数据库。如果我手动打开这个文件，它工作得很好。但是我正在尝试用PHP(laravel)来做这件事。

这是我的mysql_backup.sh文件：

#!/bin/bash

#
#   Use this script to perform backups of one or more MySQL databases.
#

# Databases that you wish to be backed up by this script. You can have any number of databases specified; encapsilate each database name in single quotes and separate each database name by a space.
#
# Example:
# databases=( '__DATABASE_1__' '__DATABASE_2__' )
databases=('sasty')

# The host name of the MySQL database server; usually 'localhost'
db_host="127.0.0.1"

# The port number of the MySQL database server; usually '3306'
db_port="3306"

# The MySQL user to use when performing the database backup.
db_user="root"

# The password for the above MySQL user.
db_pass=""

# Directory to which backup files will be written. Should end with slash ("/").
backups_dir="C:/Users/Kapil/backup/"

backups_user=""

# Date/time included in the file names of the database backup files.
datetime=$(date +'%Y-%m-%dT%H:%M:%S')

for db_name in ${databases[@]}; do
        # Create database backup and compress using gzip.
        C:/xampp/mysql/bin/mysqldump -u $db_user -h $db_host -P $db_port --password=$db_pass $db_name | gzip -9 > $backups_dir$db_name--$datetime.sql.gz
done

# Set appropriate file permissions/owner.
chown $backups_user:$backups_user $backups_dir*--$datetime.sql.gz
chmod 0400 $backups_dir*--$datetime.sql.gz

我使用PHP代码来实现这一点

shell_exec('/path/to/my/file');

但它不起作用。但是，shell_exec('ls')工作正常。如何解决我的问题？

Answer 1

php.ini

disable_functions =exec、passthru、shell_exec、system、proc_open、popen、curl_exec、curl_multi_exec、parse_ini_file、show_source

删除shell_exec
